Read This First: Rubies Are Farmable, Nothing Is Tradable
Nothing in Seven Knights Re:BIRTH can be traded, gifted or transferred between players. Rubies, Gold and Topaz are account-bound, there is no player marketplace, and Netmarble’s Terms prohibit transfers outright (§4.5). Anyone advertising “Rubies delivered to your account” is advertising a transfer Re:BIRTH does not support — the real third-party options, whole accounts and a login-delivered top-up, are covered with their warnings in our Seven Knights Re:BIRTH buying guide.
GameWith’s shop guide sets out what Rubies are for: Hero Summon (the gacha), Key Bundles, the Shop, and expanding inventory. The price that organises all farming is the summon: GameWith’s daily-missions guide states it plainly — a 10× Hero Summon costs 1,000 Rubies. A separate per-single-pull Ruby price was not found in the sources opened for this guide, so none is printed here.
The second organising fact is pity, from GameWith’s beginner guide: Hero Summon gives a 50% chance of the Rate Up or Wish List hero on the 100th pull, and a guaranteed one on the 200th pull, and pity progression carries over to the next Rate Up banner. A farmed Ruby bank is therefore never wasted progress — every 1,000 Rubies is ten pulls banked toward a guarantee that does not reset when a banner changes.
Ruby Farming: 20 Rubies per Hero at Lv. 30
The core loop is disarmingly simple, and GameWith’s guides describe it the same way everywhere: raise a hero to Lv. 30 and claim 20 Rubies from the hero-level-up rewards. GameWith’s Ruby Farming efficiency guide puts the maths underneath it: a hero needs 12,500 EXP to go from Lv. 1 to Lv. 30, so a four-hero levelling party that finishes a set earns 80 Rubies per 12,500 EXP gained — one strong farmer carrying heroes who exist to be levelled, claimed, and then used as the enhancement and fusion material the leveling guide needs.
Where you run matters, and the same efficiency guide publishes the comparison (EXP per run, before any support bonuses):
| Farming location (GameWith efficiency guide) | EXP | Gold / notes |
|---|---|---|
| Event stage A-6 | 1,250 | 4,300 Gold; event currency can drop |
| Adventure 14-1 | 1,150 | 5,100 Gold; fewer runs to max level from here |
| Adventure 19-1 | 1,180 | 5,100 Gold; Gold Boxes can drop |
| Adventure 7-1 | 940 | 1,900 Gold; the early option, where higher-star heroes start dropping |
| Nightmare stages | 1,180 | The later game’s standard EXP; farm the furthest stage you clear stably |
GameWith’s own sequencing is the practical takeaway: farm Event stages first when one is running (they unlock after clearing Adventure 4-20, per the same guide), use 7-1 while you still need heroes, and treat 14-1 onward as the serious farming tier, because the runs needed to reach max level drop there. In Nightmare, farm whichever of the furthest stages you clear stably rather than the single highest one you sometimes beat.
Keys: The Fuel, and the Bundle Maths
Adventure runs are gated by Keys: GameWith’s shop guide’s value table prices a run at 6 Keys on Normal and 12 Keys on Nightmare. Keys also recover over time — the efficiency guide notes 1 Key every 3 minutes — but serious Ruby Farming buys them back with the Rubies it earns, which is the loop’s whole engine.
The Ruby Exchange Shop is where that happens, per GameWith’s shop guide: one free Key Bundle (60 Keys) every day, plus up to 20 Key Bundles a day at 50 Rubies each — a consistent 1.2 Keys per Ruby, with the shop guide noting the price does not rise with bulk. The efficiency guide adds its own, separate recommendation for the shop’s Key Boxes: buy up to the 80-Ruby Key Box as the standard daily stopping point, and treat the 100-Ruby tier as a deliberate choice rather than a default — its balance charts show the deeper tiers running at a Ruby loss in most areas, bought back only by the side rewards (Gold, heroes, event progress) the runs also produce.
- Claim the free bundle first, every day — 60 Keys for nothing is the day’s first farm.
- Do the 12,500-EXP check before buying deep: if a levelling set earns 80 Rubies and the next Keys cost more than the set returns in your area, you are spending Rubies to farm, not farming them — sometimes right for the side rewards, never by accident.
- Keep the summon bank separate. Rubies earmarked for a 1,000-Ruby 10× pull are not Key money; the loop funds its own Keys first and banks the surplus.
Daily Missions & the Free Shop Drip
Underneath the loop sits a fixed daily drip that costs no Keys at all. GameWith’s dailies guide lists the Daily Mission rewards by points — any five of its listed missions complete the 100 points:
| Daily Mission points (GameWith) | Reward |
|---|---|
| 20 | Gold ×100,000 |
| 40 | Keys ×20 |
| 60 | Common Hero Summon Card ×5 |
| 80 | Keys ×40 |
| 100 | Rubies ×100 |
That is 100 Rubies a day for missions the guide describes as easy to hit naturally while doing your dailies — a tenth of a 10× summon, every day, before a single Adventure run. The same guide adds two shop habits: from Home > Shop > Ruby you can receive 30 free Rubies a day, alongside the free Key Bundle above, and the General Shop refreshes every 12 hours with free items worth claiming twice daily. GameWith’s web-shop guide adds one more: the official Web Shop’s Daily Tarot Draw, one free draw a day with rewards sent to your in-game mail. None of these is large; together they are the floor the farming loop stands on.
Story, Events, Arena, Tower & Guild
GameWith’s shop guide’s “How To Get Rubies” list names the remaining standing routes, and this guide follows it rather than inventing new ones: Adventure and story first-time clears (first clears on Nightmare pay Rubies too), weekly and challenge missions and achievements alongside the dailies, Arena — its weekly rank rewards pay Rubies based on tier, so even a modest climb is worth banking weekly — the Tower of Trials, where each floor cleared rewards Rubies, and events and passes, which the shop guide lists among Ruby sources alongside daily and weekly missions.
Guild play belongs on the same list for its fuel rather than a direct Ruby payout. GameWith’s dailies guide notes guilds unlock after clearing Adventure 4-10, that a daily guild check-in pays Keys the next day scaled by how many members check in — from 10 Keys at one or more check-ins up to 60 Keys at 25 or more — and that guild missions run daily (individual) and weekly (cooperative). Its beginner guide adds the content side: joining a guild opens Castle Rush, Advent Expedition and Guild War, whose exchange currencies buy their own shops’ goods. In farming terms, a live guild is a daily Key subsidy for the Ruby Farming loop — which is why “join a guild” is farming advice in this game, not just social advice.
Spending Farmed Rubies: Summons First, Honestly Priced
A farmed bank has three honest destinations, in the order GameWith’s own guides imply. First, its own fuel: the Key Bundles and Key Boxes of the Keys section, bought only as deep as your area’s EXP maths supports. Second, summons: 1,000 Rubies per 10× pull, against pity that carries over — 100 pulls for the 50% point, 200 for the guarantee — which makes patient banking rational in a way it is not in games where pity resets. Third, the shop: GameWith’s shop guide lists the Ruby Exchange Shop’s other standing offer, the Power Up Pack at 100 Rubies (a Common Hero Ticket, 5 Topaz and 100,000 Gold), and describes Topaz — otherwise earned mainly from events, missions and premium-purchase bonuses — as the slow currency behind the Topaz Shop’s Awakening Materials, Skill Stones and Summon Tickets.
What not to do with the bank is just as sourced: do not convert it into someone else’s. There is no transfer function to convert it with, and the buying guide covers what offers claiming otherwise actually are.
Buying Rubies & Accounts
The legitimate money-in routes are Netmarble’s own: in-app purchases, and the Official Web Shop, which sells Prisms spent in game at the same total cost as buying directly — see the buying guide for the full picture. The third-party market wired on the Seven Knights Re:BIRTH game page is Eldorado, PlayerAuctions and IGVault accounts — whole-account and reroll sales that Netmarble’s Terms prohibit (§5.5(j)) — and LootBar Ruby top-up, which is login delivery: a seller signs into your account, the conduct §3.3 prohibits, and the warning is carried prominently in the buying guide for a reason. Farming is slower than all of that and safer than all of that, and in this game — uniquely — the farm is the design: the developers named a whole system after it.
Frequently Asked Questions
How do you farm Rubies in Seven Knights Re:BIRTH?
By Ruby Farming: raise heroes to Lv. 30 and claim 20 Rubies per hero from the level-up rewards. A hero takes 12,500 EXP from Lv. 1 to Lv. 30 (GameWith), so a four-hero levelling set earns 80 Rubies per batch. Fuel it with Keys — one free 60-Key Bundle daily, plus bundles at 50 Rubies — and farm Event stages, then Adventure 14-1 onward, then Nightmare.
How many Rubies do daily missions give?
100 Rubies a day at 100 Daily Mission points (GameWith’s rewards table: 100,000 Gold at 20 points, 20 Keys at 40, five Common Hero Summon Cards at 60, 40 Keys at 80, and 100 Rubies at 100). Add 30 free Rubies a day from the in-game Shop and the official Web Shop’s free Daily Tarot Draw.
How much does a summon cost, and how does pity work?
A 10× Hero Summon costs 1,000 Rubies (GameWith). Pity gives a 50% chance of the Rate Up or Wish List hero on the 100th pull and a guaranteed one on the 200th pull, and progression carries over to the next banner — so a farmed bank is never wasted. No sourced per-single-pull Ruby price was found, so this guide does not print one.
Can you buy farmed Rubies from another player?
No. Rubies cannot be traded, gifted or transferred between accounts, and Netmarble’s Terms prohibit transfers (§4.5). What marketplaces actually sell is whole accounts and rerolls — prohibited by §5.5(j) — and one login-delivered top-up, which hands a seller your login. The safe supply is the farm above plus Netmarble’s own Web Shop and in-app purchases.
