We make Idle Ronin, so these numbers are the real ones.
Daily diamonds
| Source | Diamonds | How often |
|---|---|---|
| Daily quests | 70: 20 for 150 enemies, 20 for 5 bosses, 30 for 2 videos | Every day |
| ALL QUESTS CHEST | 50, plus 3 Unit Cores | Every day |
| Crystal Mine | 20 + 3 per level, up to 100 a win | 2 keys a day, plus a bonus key |
| Free diamonds in the shop | 20 | Every 30 minutes |
| Daily offer | 40, plus gold | Once a day |
| Supply drop | 10 to 25, in 45% of drops | Every 4 hours |
| Login calendar | 30 on day 1, 50 on day 4, 150 on day 7 | Every 7 days you log in |
Daily quests and the calendar open at stage 3 and dungeons at stage 10. Missing a day does not reset the calendar, and the supply drop and login reward need an internet connection.
Weekly diamonds
| Source | Diamonds |
|---|---|
| Weekly quests | 450: 100 for 1,000 enemies, 150 for 10 dungeon or tower wins, 200 for opening 30 Unit Cores |
| Weekly chest | 300, plus 10 Unit Cores |
| Neon Tower floors | 130 by floor 15, 580 by floor 40, 1,930 by floor 100, 10,480 by floor 300 |
| Neon Tower ranking | 50 to 1,000, from floor 5 |
The Neon Tower is the biggest source by far, and its floor rewards come back every week. Our Neon Tower guide shows how to climb it and how the weekly ranking works.
Season, achievements and events
- Cyber Pass: the free track pays 480 diamonds every 28-day season, plus Unit Cores and gold.
- Achievements: 51 achievements pay 1,740 diamonds in total, 10 to 150 each.
- Side-Jobs, from stage 65: some jobs pay diamonds instead of gold.
- Neon Halloween, 20 October to 10 November: 10 diamonds per trade, at a price that rises each time.
- Cyber Christmas, 10 to 31 December: 300 diamonds among the gadget rewards.
How many diamonds a day is realistic?
Quests, the calendar and the supply drop alone come to about 200 a day. Add two or three Crystal Mine wins, the daily offer and some shop videos, and an active player collects several hundred diamonds a day, plus 750 a week from weekly quests and the weekly chest, plus whatever the Neon Tower pays.
Best ways to spend diamonds
- x2 ATK for good, 1,000 in BOOSTS & PACKS. It doubles the ATK of every unit forever. Buy it first.
- +100% Rebirth Tokens for good, 800. Every later Rebirth pays twice.
- x2 Enemy Gold for good, 1,000.
- Energy Cells in the item shop: 25 diamonds for 4 copies of a unit.
- Instant Rebirth, 150, at the end of a long run: the full token reward without the reset.
- Unit Cores: 90 for 1,600 diamonds is the best rate at about 18 each, against about 27 in the 3-core pack.
- Skins: each adds +10% ATK, and the cheapest cost 450 and 500.
Avoid finishing crafts early at 1 diamond per minute, re-rolling white equipment, which has nothing to re-roll, and Adaptive Cores, which Blank Chips beat. Our item shop guide and rebirth guide go deeper.
