Unit Mutations
Roll Anime to Fight mutations explained — normal, shiny, gold, and diamond variants with stat boosts and roll strategies.
Mutation system basics
Mutations overlay rarity in Roll Anime to Fight. When you roll a unit, it may arrive as normal, shiny, gold, or diamond variant. Each tier increases stat multipliers and adds visual effects. Mutations persist through merges on the base unit — diamond stays diamond when merging matching fodder.
Code rewards grant guaranteed diamond-tier units without rolling. Random diamond mutations from rolls are the rarest gacha outcome, hunted during luck-boosted sessions and events.
Tier-by-tier breakdown
Normal: baseline stats, no bonus multiplier. Shiny: small boost, common enough to see within first 50 rolls. Gold: meaningful boost, target for mid-game accounts without code diamonds. Diamond: maximum boost, code-accessible or roll-chased.
Mutation tier is independent of character identity — diamond on weak character underperforms gold on S-tier legendary. Always mutation-upgrade on tier list-approved units.
Rolling and upgrading mutations
You cannot directly upgrade shiny to gold via menu — typically need new roll or event item unless future patches add upgrade stones. Plan long-term: build code diamond first, roll gold/diamond on desired legendary second. See diamond mutations guide for luck investment curves.
