Be The Final Boss Mutations
Shiny, Cursed, Demonic — ATK/HP only. Roll on summon; Cursed Moon doubles the luck.
By Bloxron Editorial Team · Last updated
Mutations roll on Altar summon and only change ATK/HP — kit and range stay the same. Demonic landed in Update 1; if your client shows a different %, trust Unit Index.
Mutation table
| Mutation | ATK/HP | Note |
|---|---|---|
| Shiny | +30% ATK/HP | Early bump |
| Cursed | +100% ATK/HP | What mid-game clears want |
| Demonic | +150% ATK/HP (confirm in-game) | UPD1 top mutation; rare |
- Only ATK/HP change — skills and range stay the same.
- One mutation per unit, rolled on summon. You can’t add it later.
- Cursed Moon or the 159 Robux Double Mutation pass = ×2 mutation luck.
- Altar Luck helps rarity, not mutation chance.
How to raise odds
| Method | Detail |
|---|---|
| Cursed Moon | Free ×2 mutation luck while the weather is up — save Souls and roll |
| Double Mutation Chance | 159 Robux shop pass — permanent ×2 on Altar rolls |
Roll plan
- Stabilize the line. Don’t burn Souls while Wave 25 still deletes you. Hold a real frontline first.
- Bank for Cursed Moon. Quiet stretches are for saving. When the purple window hits, roll the roles you actually field.
- Keep the better copy. A mutated copy of a unit you use beats a plain higher-rarity filler you never place.
- Shard the keepers. Fusion Shards go into mutated units you field — not every junk roll.
FAQ
Can I add a mutation later?
No. One mutation per unit, rolled on summon. Keep or replace — you don’t slap Cursed onto a plain copy later.
Shiny vs Cursed vs Demonic?
Shiny +30%. Cursed +100% is the mid-game target. Demonic +150% (confirm in-game) is rare top end.
Mutated Bone Grunt or fresh Iron Skeleton?
Mutations juice stats, not role. A Cursed Bone Grunt can outlast a plain Iron Skeleton for a while — still swap when the role fails.
Does Altar Luck help mutations?
No. Altar / Summon Luck raises rarity. Mutation chance is Cursed Moon or the Double Mutation pass.
