Sky Fever Season 2026 ended on October 25, 2026 — this guide does not pretend otherwise. The season ran September 1 to October 25, 2026, and its rewards window closed October 26. What follows is two things: a complete record of what the season gave and how its energy loop worked (so you know exactly what to do when it returns — it is an annual event), and the durable energy economy that the season was built on, which is live right now and is the real farming game in Summoners War. If you arrived after October 25, skip to the energy sections: they are worth more than the season ever was. If you played the season, the Fever Token math here is the post-mortem that tells you whether you spent well.
Summoners War: Sky Arena is a turn-based monster-collection RPG from Com2uS (2014, live on mobile and Steam PC), and it is not an MMO. Its farming game is not about killing monsters for gold — it is about spending Energy in the right dungeons to get runes, spending Mana Stones to power those runes up, and spending Crystals on the things that multiply both. Three currencies, three jobs, and the players who confuse them are the players who stay poor. This guide keeps them strictly separate, works the full math of the Sky Fever energy loop, and gives you a daily routine that turns Energy into runes into progression without spending a cent.
The Three Currencies (Do Not Mix These Up)
| Currency | What it is | How you earn it | What it buys | Never spend it on |
|---|---|---|---|---|
| Energy | Stamina — the action currency | Regen 1 per 5 min; missions, events, level-ups, Temple of Wishes | Scenario, Cairos Dungeon, ToA, Guild Battle, Rift, World Boss, Dimensional Rift entries | Nothing — it is spent by playing, not in a shop |
| Mana Stones | Main in-game currency | Battles, selling runes, events, Arena | Rune power-ups, summoning (10,000 per Mystical Scroll), crafting, shop | Powering flat-stat runes on slots 2/4/6 |
| Crystals | Premium currency | Events, Arena, ToA, missions, purchases | Energy refills, Premium Pack (750 = 11 Mystical Scrolls), shop | Impulse scroll packs and shop scrolls |
Three more currencies you will meet, none of which convert into the three above: Glory Points (Arena — scrolls and Devilmon pieces, now that the glory buildings are gone), Guild Points (guild content), and Ancient Coins (used for monsters like Fran and for the Sky Fever Ancient Coin 5★). Fever Tokens were the Sky Fever seasonal currency — they existed for the season and died with it. And Dimension Hole Energy is a separate stamina pool entirely: 1 per battle in the Dimension Hole, regenerating 1 per 2 hours, starting at a 90 maximum. Energy is not used for Arena or World Arena — those run on wings.
Energy: The Full Economy
Energy is the throttle on everything. Understand it and you understand the farming game.
The numbers (official, v8.1.4, November 2023)
| Fact | Value | Source / note |
|---|---|---|
| Regeneration | 1 Energy per 5 minutes (12/hour) | Long-standing; unchanged by the revamp |
| Max storage, Summoner Lv 1 | 92 | Was 42 before v8.1.4 — old guides are wrong |
| Max storage, Summoner Lv 100 | 240 | Was 140 at the old Lv 50 cap |
| Max storage, all bonuses | 310 | Statues + Daily Pack I on top of the 240 base |
| Full refill time (240 bar) | 20 hours passive | 1 per 5 min — this is why free Energy sources matter |
| Level-up | Full Energy restore | The classic loop: spend to empty, level, spend again |
| Crystal refill | 30 Crystals (reported) | Pre-revamp figure; v8.1.4 added a 290-Energy charge package — price relationship unverified, see note |
The refill-price caveat: the 30-Crystal energy refill is reported by the SpokLand currency reference, which predates the v8.1.4 revamp. The official v8.1.4 notes mention a new package that charges 290 Energy at once (300 with Daily Pack I’s +10 storage), but do not state its Crystal price in the material checked. This guide reports the 30-Crystal figure as the long-standing price and flags that it has not been re-verified against the post-revamp shop. Check the in-game price before budgeting Crystals around it.
Where free Energy comes from
- Passive regen: 12 per hour, 288 per day if you never cap out. Capping out is the leak — Energy stops regenerating at maximum, so every hour spent at full Energy is 12 Energy thrown away. Spend before you sleep, spend when you wake.
- Level-ups: a full restore every Summoner level. Early on, levels come fast enough that this is a major Energy source. Bank nothing — spend, level, spend.
- Missions and events: daily missions, the Summoner’s Way questline, and every seasonal event pay Energy in flat chunks. Sky Fever’s shops sold Energy +50 (limit 10) and Energy +20 with no limit in the Bonus Shop.
- Arena and the Temple of Wishes: Arena rewards and the daily free wish both pay Energy. The wish is one tap a day — never skip it.
- Repeat Battle: up to 30 repeats per run now (raised from 10). Set a 30-repeat farm, walk away, and let the Energy convert itself into runes while you do something else.
The daily Energy budget
A free player who never caps out and claims dailies has roughly 300–400 Energy a day to spend (288 passive + missions + events + wishes). That is the budget the rest of this guide is built around. A player who caps out for eight hours overnight loses ~96 Energy a day — nearly a third of the budget — to nothing. The single highest-value habit in this guide is not a dungeon or a purchase. It is spending your Energy before bed.
Sky Fever Season 2026: What It Was
Sky Fever is Summoners War’s annual progression event, run as part of the game’s 12th-anniversary celebration in 2026. Six events, one season, September 1 (7:00 PM PDT) to October 25 (7:59 AM PDT), 2026, with rewards claimable until October 26.
| Event | What it gave | Who it was for |
|---|---|---|
| Monster Fever Summon | One default 5★ at MAX skill / 6★ / Lv 40 / Awakened, from a list of 15 (Water/Fire/Wind); one free switch if summoned before Sep 19 PDT | Everyone — the headline reward |
| Fever Mission Clear | Seven max-level fusion monsters + one 5★ Ancient Coin monster (6★/Lv 40/max skills/runed) | Players who cleared content missions |
| Rune Set Crafting | One 6★ Legend Rune Set per day, up to 54 total — choose type + main property, high-value properties guaranteed | Everyone — the best rune payout of the year |
| Fever Shop (Gold & Silver Packages) | Free Fever Gold/Silver Packages via Fever Tokens — Legendary All-Attribute Scrolls, Devilmon, growth items | Everyone who earned Fever Tokens |
| Arena & Guild Challenge | Light & Darkness Scrolls, Devilmon, medals, points from PvP and guild entries | PvP and guild players |
| Special Check-in + Fever Shops | Daily login rewards; Fever Premium/Growth shops; Bonus Shop after buying everything | Everyone who logged in |
New and returning summoners got more: a daily +15 6★ Rare rune set and 1,000,000 Mana Stones, every day of the season. If you were new or returning in September 2026, the season handed you a competitive account in weeks. That is the point of Sky Fever — it is not a content event, it is a catch-up event, and Com2uS runs it annually. The 2025 season returned alongside the Challenge Battle mode; the 2026 season was bigger, with 15 summonable 5★ monsters instead of fewer. Expect the next one around the same time of year — no 2027 dates have been announced.
Fever Token Math: How the Energy Loop Paid
Fever Tokens were the season’s currency, and Energy was how you earned them. The exchange rates are the heart of the season’s farming game.
| Method | Fever Tokens | Limit | Efficiency |
|---|---|---|---|
| Use Energy mission | 20 per 100 Energy used | Up to 50 times (1,000 tokens max) | The main engine — farm as normal, get paid |
| Content drops | 1–3 per drop, based on Energy used | Ongoing during the season | Passive bonus on top of farming |
| Use 100 Crystals | 20 tokens | Per 100 Crystals spent | Only for players already spending Crystals |
| Scout Battle, 1 hour | 5 tokens | Per hour run | Slow — background income only |
| Daily check-in + Energy missions | Daily amounts | Reset daily at 8:00 AM PDT | Never miss a day — the reset is the tax |
Work the main engine: 1,000 Fever Tokens from the Use Energy mission required 5,000 Energy spent during the season — about 90 Energy a day across the 55-day season, which is less than a third of a free player’s daily budget. In other words, the season paid its full token mission to anyone who simply played normally and spent their Energy. The players who missed out were not the players who farmed too little — they were the players who let Energy cap out, or who did not log in daily and lost the check-in resets.
The Crystal route was a trap for free players. 20 tokens per 100 Crystals is a bad exchange if you are buying Crystals to spend them — the same Crystals buy Energy refills that earn tokens through the Use Energy mission anyway. Only spend Crystals on tokens if you were already spending those Crystals on refills during the season.
What the Fever Shop Was Worth
Fever Tokens bought Fever Gold and Silver Package Tickets, exchanged for free Fever Gold and Silver Packages. The shop also sold Energy directly, and a Bonus Shop opened after you bought everything in the main shops.
| Shop item | Value | Priority |
|---|---|---|
| Fever Gold Package | Legendary All-Attribute Scroll, Devilmon, growth items | First — the Devilmon alone is worth it |
| Fever Silver Package | Growth items, scrolls | Second |
| Energy +50 (limit 10) | 500 Energy for tokens | Buy — Energy converts to more tokens and more runes |
| Dimension Hole Energy +30 (limit 5) | 150 Dimension Hole Energy | Buy if you run Dimension Hole |
| Bonus Shop: Energy +20 (no limit) | Unlimited Energy for leftover tokens | Last — the token sink for everything left over |
The rune crafting event was the quiet best reward of the season. One 6★ Legend Rune Set per day, up to 54 sets, with your choice of type and main property and high-value properties guaranteed on each craft. Fifty-four crafted Legend sets is a year’s worth of rune progress compressed into a season — and unlike the summon or the packages, it asked nothing except showing up daily. If a future Sky Fever runs the same event, the daily craft is the single highest-priority action in the game for the season’s duration.
Rune Farming: Where Your Energy Actually Goes
When no event is running — which is most of the year — your Energy goes to Cairos Dungeon. The order is the same ladder as the leveling guide, but the farming lens changes what “done” means: you never finish farming runes. You farm them forever, and the only question is which dungeon pays best today.
| Dungeon | Rune sets | Farm it when | Notes |
|---|---|---|---|
| Giant’s Keep (GB12 / Abyss Hard) | Swift, Despair, Fatal, Blade, Energy | Always — the default farm | Swift is the most-used set in the game; you never have enough |
| Dragon’s Lair (DB12 / Abyss Hard) | Violent, Revenge, Will, Focus, Guard, Endure | Once Giants is consistent | Violent is the endgame standard — the long farm |
| Necropolis (NB12 / Abyss Hard) | Rage, Vampire, Nemesis, Destroy, Fight | Once Dragons is consistent | Rage/Vampire for damage dealers and PvP |
| Steel Fortress / Punisher’s Crypt | Determination, Enhance, Accuracy, Tolerance, Guard, Will | Mid-to-late game | Artifact and 2nd-Awakening era dungeons — later |
| Scenario Hell stages | Scenario rune sets + fodder EXP | Early game, and for leveling fodder | Your farmer clears these to level 6★ fodder |
A note on per-run Energy costs: this guide does not state Energy costs per Cairos run, because no source checked for this guide publishes a verified current figure, and the costs have changed across updates. Do not trust a guide that quotes a per-run cost without a source — check the cost on the dungeon screen in the game. What is verified is the shape: higher floors cost more Energy per run and drop better runes, and Abyss Hard is the top of the ladder.
Rune selling is Mana income. Most runes you farm are not keepers — sell them. A flat-stat slot 2/4/6 rune, a rune with no Speed substat, a 4★ rune past your early game: all Mana Stones. Mana is the currency that powers up the keepers, and the farm funds its own upgrades this way. The loop is Energy → runes → sell the bad ones for Mana → power up the good ones.
Mana Stones: Earning and Spending
Mana Stones are the currency you will always be short of, because rune power-ups are the biggest Mana sink in the game and the cost climbs with every level.
- Earn: dungeon runs, selling runes, Arena rewards, events, Scenario clears, the World Boss. The Sky Fever season paid new and returning players 1,000,000 Mana Stones a day — that is what a catch-up event looks like, and it is why seasonal events matter more than any daily farm.
- Spend: rune power-ups first, summoning second (10,000 Mana per Mystical Scroll summon), crafting and shop purchases third.
- The +15 rule: do not power a rune to +15 unless it is 5★ or 6★ with good substats. Powering to +12 is cheap; +12 to +15 is where the Mana goes. A rune that is not worth +15 is not worth +13 either — stop at +12 and move on.
- The slot rule, again: percentage primaries on slots 2, 4, and 6 (except flat Speed on slot 2). Mana spent powering a flat Attack slot-6 rune is Mana burned — sell the rune instead.
Crystals: Earning and Spending
Crystals are the premium currency, and the spending discipline around them is the difference between a free account that progresses and a free account that stalls.
| Crystal use | Cost | Verdict |
|---|---|---|
| Energy refill | 30 Crystals (reported, pre-revamp — verify in-game) | Best use. Energy becomes runes; runes become progression. |
| Premium Pack | 750 Crystals = 11 Mystical Scrolls + bonus items | Defensible — the only scroll purchase veterans defend. Still debated vs refills. |
| Shop scrolls / impulse summons | Varies | Worst use. The expected value is terrible; refills beat it. |
| Event token conversion (Sky Fever) | 100 Crystals = 20 Fever Tokens | Only if already spending on refills — never as a standalone purchase. |
Where Crystals come from (free): events (the largest source — Sky Fever, collaborations, anniversary events), Trial of Ascension clears, Arena weekly rewards, missions, the Temple of Wishes, and World Boss loot. A disciplined free player banks Crystals between events and spends them on refills during rune-farming pushes. The veteran rule is one sentence: Crystals buy Energy, Energy buys runes, runes buy everything else.
Summoning Math: What Your Scrolls Are Actually Worth
Farming produces scrolls — Mystical Scrolls from dungeons, ToA, shops, and events — and the math on what they pay is fixed, published, and brutal.
| Mystical Scroll outcome | Rate | What it means |
|---|---|---|
| Natural 3★ | 91.5% | Nearly every pull. Fodder, skill-ups, or fusion material. |
| Natural 4★ | 8.0% | About 1 in 12. The workhorses — many core monsters are nat 4s. |
| Natural 5★ | 0.5% | About 1 in 200. The lottery ticket. |
| Already awakened | ~2% | Small bonus on any pull. |
Each Mystical Scroll summon also costs 10,000 Mana Stones. There is no hard pity: every scroll rolls independently, and no number of failed pulls guarantees a nat 5. Special Summon rate-ups focus the pool on a new monster family but do not change the 0.5% rate. The practical consequences: never summon one scroll at a time hoping to get lucky — save scrolls for rate-up events on a family you want, and never spend Crystals to chase a specific nat 5. The farmable team (Veromos, Sigmarus, Bernard, Shannon, Belladeon, Loren, Fran, Kro) clears the content without a single lucky pull — that is the design, and the summoning lottery is the decoration on top of it.
Duplicate nat 5s convert into Splendid Blessings of Summon, the game’s bad-luck mitigation — a duplicate lets you choose between two nat-5 outcomes on a future summon. It softens the variance; it does not remove it.
The Daily and Weekly Energy Loop
| When | Do this | Energy / cost |
|---|---|---|
| Morning | Spend down to near-empty on your current farm (Giants first) | Full bar → runes |
| Morning | Temple of Wishes (one free wish) | Free |
| Morning | Arena wings — use them all | No Energy — separate refill |
| Midday | Check missions; claim Energy rewards | Free Energy |
| Evening | Repeat Battle ×30 on your farm while doing something else | Bulk Energy → bulk runes |
| Evening | World Boss when available | No Energy — free loot |
| Before bed | Spend to empty again — never sleep at full Energy | ~96 Energy saved per night vs capping out |
| Weekly | Rune-removal day: re-rune, sell the bad runes for Mana | Mana Stones for power-ups |
| Monthly | Trial of Ascension climb (resets monthly) | Devilmons, scrolls, Crystals |
| Seasonal | Events (Sky Fever, collaborations, anniversary) | The biggest free payouts in the game — never miss one |
Farming Traps
- Sleeping at full Energy. Eight hours capped out is ~96 Energy lost — nearly a third of a free day’s budget. The most expensive mistake in the game costs nothing to fix.
- Spending Crystals on shop scrolls. Refills beat scrolls. Every time. The math is not close.
- Powering runes past +12 without good substats. The Mana cost from +12 to +15 is the steepest part of the curve, and a bad rune at +15 is still a bad rune.
- Farming a dungeon you cannot clear consistently. A 70% clear rate wastes 30% of your Energy on failed runs. Drop a floor until you clear 95%+, then climb back.
- Hoarding Fever Tokens (or any event currency) past the event. Event currencies expire. Spend them before the season ends or lose them.
- Summoning one scroll at a time. Save for rate-ups on a family you want. The 0.5% rate does not care about your patience — but the focused pool does.
- Trusting pre-2023 Energy figures. Max storage 140, base 42, glory-building advice — all dead since v8.1.4. If a guide quotes them, it is stale.
- Buying the Premium Pack before your Giants team works. Eleven scrolls will not fix a team that cannot farm. Runes first, scrolls second.
Crystal Income: Where Free Crystals Come From
Energy refills are the best Crystal purchase, so the next question is where free Crystals come from. The answer is events — overwhelmingly.
| Source | Crystals | Notes |
|---|---|---|
| Seasonal events (Sky Fever, collaborations, anniversary) | Largest source | Sky Fever paid bonus Crystals and points from PvP and guild content; collaboration events pay similarly |
| Trial of Ascension | Per clear, monthly | Climb every month — the Crystals are part of the prize |
| Arena weekly rewards | Weekly | Participate, collect, repeat — free Crystals for wings you were spending anyway |
| Missions + Temple of Wishes | Small, steady | Daily trickle — never skip the wish |
| World Boss loot | Variable | Free loot for zero Energy |
| First-clear rewards | One-time | Scenario, dungeons, and content first-clears pay Crystals — another reason to clear everything once |
The banking rule: free Crystals are worth more during events than between them, because events multiply what Crystals buy (refills during a Fever-style Use Energy mission earn tokens on top of runes). Bank Crystals between events; spend them on refills during events. A player who refills randomly through the year gets runes. A player who refills during events gets runes and event rewards.
Rune Keep-or-Sell Rules
Most runes are not keepers. Deciding fast is a skill — every second spent agonizing over a bad rune is a second not farming the next one.
| Rune | Keep | Sell |
|---|---|---|
| 6★, slot 2/4/6, % primary | Yes — check substats | Only if all substats are flat and useless |
| 6★, slot 2/4/6, flat primary | Only flat Speed on slot 2 | Everything else — Mana Stones |
| 6★, slot 1/3/5 | Yes if it has Speed substat | No Speed and no useful % substats |
| 5★, good substats | Early game only | Once your team is in 6★ runes |
| Any rune, no Speed substat, late game | Only for niche sets (Will, Nemesis) | Usually — Speed is the stat |
| Legend rune, any slot | Almost always — check it twice | Almost never |
The Speed test: a rune’s value is mostly its Speed substat. A 6★ Swift rune with +18 Speed is a keeper even if the other substats are mediocre. A 6★ rune with no Speed and three flat substats is Mana Stones wearing a rune’s clothes. When in doubt, ask one question: does this rune make something faster? If not, sell it.
Grindstones and Gems: The Rune Endgame
Once your runes are powered to +15, the next upgrade is not a new rune — it is improving the one you have. Grindstones and gems, earned from the Rift of Worlds raids, add flat or percentage substats to a rune’s existing substats (grindstones) or replace a substat entirely (gems).
- Where they come from: Rift of Worlds raid battles (three-player co-op) and their crafting. This is mid-to-late game content — do not chase it before your Giants and Dragons teams are consistent.
- What to grind first: Speed substats on your fastest Swift and Violent sets. A +10 Speed grindstone on four runes is +40 Speed on a monster — the difference between moving first and moving second.
- What not to grind: flat substats on runes you will replace. Grindstones are rarer than runes; spend them on keepers, not placeholders.
- The Homunculus is the Rift’s other prize — a craftable monster whose skills you choose. A late-game project, and a good one, but not a first-year goal.
2026 Event Recap: The Year in Free Rewards
Events are the biggest free payouts in Summoners War, and 2026 was a heavy year. Knowing the pattern tells you what to expect next year.
| Event | When (2026) | What it paid |
|---|---|---|
| Sky Fever Season | Sep 1 – Oct 25 | Free maxed 5★, 54 crafted Legend rune sets, Fever Packages, Devilmon, daily rune sets + 1M Mana for new/returning |
| Frieren: Beyond Journey’s End collab | 2026 | Collaboration monsters and event rewards |
| SWC2026 Nat 5 Summon event | Oct 11 – Nov 15 | Daily energy missions; summons from 23 default nat-5 Fire/Water/Wind monsters |
| World Arena Season 39 | Oct 5 – Dec 19 | Seasonal PvP rewards; shop items carry into Season 40 |
| Challenge Battle mode | 2025–2026 | Monthly rewards by best run and total wins |
The lesson of 2026: Com2uS runs a major progression event every year (Sky Fever), a collaboration most years, and a championship summon event around SWC. The players who got the most from 2026 were not the players who spent the most — they were the players who logged in every day of Sky Fever, crafted a Legend set every day, and spent their Energy during the season. Next year’s calendar will rhyme. Be ready for it: bank Crystals, keep your Energy unspent the day before a season starts, and clear your schedule for the first week.
A Free Player’s Monthly Projection
| Resource | Per month (free, active) | What it becomes |
|---|---|---|
| Energy | ~9,000–12,000 | ~1,000+ dungeon runs (Repeat Battle ×30) |
| Mana Stones | Millions (farm + sales) | Rune power-ups to +12/+15 on keepers |
| Crystals | Several hundred (events + ToA + Arena) | Energy refills during events, or a Premium Pack |
| Mystical Scrolls | ~20–40 | ~2–3 nat 4s expected; a nat 5 every ~5–10 months on average |
| Devilmon | ~4–5 | One nat-5 skill-up every ~2–3 weeks |
Those numbers are planning figures, not promises — scroll and Devilmon counts move with events, and the nat-5 expectation is an average over hundreds of pulls, not a guarantee for any single month. But the shape is right: a free, active player progresses steadily, and the bottlenecks are runes and Devilmon, not scrolls. Spend your time where the bottleneck is.
Patch State (as of November 9, 2026)
Live now: v9.3.8 (October 28, 2026). World Arena Season 39 runs October 5 – December 19, 2026. Sky Fever Season 2026 ended October 25, 2026 — its Fever Tokens, shops, and rune-crafting event are closed, and this guide records them as the annual pattern to expect, not as live content. The Nat 5 Monster Summon event picked by SWC2026 players ran October 11 – November 15, 2026 (rewards to November 18): daily energy missions, three completions earning one summon from up to 23 default nat-5 Fire, Water, and Wind monsters. The Frieren: Beyond Journey’s End collaboration ran earlier in 2026.
What to watch: the next Sky Fever (expected annually, no 2027 dates announced), the next collaboration, and World Arena Season 40 (season-exclusive shop items from Season 39 stay on sale through Season 40). The durable facts do not change with patches: Energy is 1 per 5 minutes, the cap is 240 base / 310 max, and the farm is Giants until it is consistent, then Dragons. Everything else is a season.
Frequently Asked Questions
Is Sky Fever Season live right now?
No. Sky Fever Season 2026 ran September 1 to October 25, 2026, with rewards claimable until October 26. It is an annual event — the 2025 season ran in October 2025 — so expect it to return around the same time of year, but no 2027 dates have been announced.
What is the Energy cap in Summoners War?
Base max Energy is 92 at Summoner level 1 and 240 at level 100, up to 310 with all bonuses (statues and Daily Pack I). The cap was raised from 50 to 100 and the storage increased in the v8.1.4 update in November 2023. Energy regenerates at 1 per 5 minutes.
How do you get Fever Tokens?
During Sky Fever Season: 20 tokens per 100 Energy used (up to 50 times, 1,000 max), 1 to 3 tokens as content drops, 20 tokens per 100 Crystals spent, and 5 tokens per hour of Scout Battle. The season has ended, so Fever Tokens cannot be earned now.
What is the best use of Crystals in Summoners War?
Energy refills. The veteran rule is: Crystals buy Energy, Energy buys runes, runes buy everything else. The Premium Pack (750 Crystals for 11 Mystical Scrolls) is the only scroll purchase veterans defend, and even that is debated against refills. Never spend Crystals on shop scrolls or impulse summons.
What are the Mystical Scroll summon rates?
91.5% for a natural 3-star, 8.0% for a natural 4-star, and 0.5% for a natural 5-star, with about a 2% chance the monster arrives already awakened. Each summon also costs 10,000 Mana Stones. There is no hard pity — every scroll rolls independently.
Where should I farm runes first?
Giant's Keep — it drops Swift, Despair, Fatal, Blade, and Energy runes. Farm it until your team clears consistently, then move to Dragon's Lair for Violent sets and Necropolis for Rage and Vampire. The current top difficulty is Abyss Hard; if your team cannot clear it, farm B12 until your runes catch up.
What is the difference between Crystals, Mana Stones, and Energy?
Energy is stamina — it is spent by playing and regenerates at 1 per 5 minutes. Mana Stones are the main in-game currency, spent on rune power-ups and summoning. Crystals are the premium currency, spent on Energy refills and packs. They do not convert into each other.
Is Summoners War: Chronicles the same game?
No. Summoners War: Chronicles is a different game from Summoners War: Sky Arena. This guide covers Sky Arena only — the 2014 Com2uS game, live on mobile and Steam PC.
