Mutations in Roll Anime to Fight are roll-time power-ups. They raise a unit’s Damage, Health, and Defense, give it a new look, and stack with Traits. A unit holds one mutation max. You never stack two, and none of the current set is a debuff.
As of the Faction Update, there are eight mutations. Gold and Diamond can land on any Roll. Demon through Cursed only show up during short timed events. Astronaut is the chase pick when admins open its event.
Need more Gold or Trait Shards for rolls and upgrades? Check the Roll Anime to Fight codes page, then come back ready for the next quarter-hour window.
All eight mutations and what they boost
Percentages climb from Gold up through the timed ladder. Cursed is the strongest mutation you can farm without admin help. Astronaut leads overall on Damage and Health, even though its Defense sits a notch under Cursed.
| Mutation | Damage | Health | Defense | How you get it |
|---|---|---|---|---|
| Gold | +50% | +25% | +2% | Natural on Roll |
| Diamond | +125% | +50% | +3% | Natural on Roll |
| Demon | +200% | +75% | +5% | Demon Mutation Event |
| Destroyer | +275% | +100% | +6% | Destroyer Mutation Event |
| Hollow | +350% | +125% | +6% | Hollow Mutation Event |
| Slayer | +450% | +150% | +7% | Slayer Mutation Event |
| Cursed | +550% | +175% | +8% | Cursed Mutation Event |
| Astronaut | +650% | +250% | +6% | Astronaut event (Admin Abuse only) |
A mutated copy of a unit is always stronger on those three stats than the plain base. Treat high-tier mutations as keepers, not filler.
How to get Gold, Diamond, and the event mutations
Gold and Diamond can appear whenever you Roll. No event banner needed.
Demon, Destroyer, Hollow, Slayer, and Cursed only roll while their matching Mutation Event is live. The cycle order is Demon → Destroyer → Hollow → Slayer → Cursed.
Events can start about every 15 minutes on the quarter-hour marks. Each window lasts only about 1-2 minutes, so bank currency and open the roll UI before the clock hits.
Units already sitting on your base do not gain a mutation when an event starts. Only new rolls and summons during the live window can pick it up.
Astronaut is not in the normal rotation. It only appears when admins force an Astronaut mutation event (often during Admin Abuse). Watch the in-game Event button and server announcements instead of chasing a fixed calendar date.
A few things raise your chances, even though exact drop rates stay hidden:
- Spend Coins on Luck upgrades so more rolls land special outcomes.
- Check the Shop for the 2x Mutation and 2x Luck gamepasses if you want paid luck boosts.
- Roll hard only while the event you care about is live, especially for Cursed.
Keep rules stay simple. Prefer a mutated copy over a plain base of the same unit. If you merge, match the same unit, same level, and same mutation (for example two Level 1 Cursed copies). Do not feed a rare mutation into a plain merge path.
After you lock a strong mutation, send the unit through the Trait Machine with Trait Shards for another power layer. Mutations and Traits stack; they do not replace each other.
