Wiki · Mutations
From Big to Void: each mutation makes your pet stronger and adds a battle bonus.
01 — How to mutate
Grab food until the Growth bar hits 100 and press MUTATE. The new mutation replaces the old one, so it can go up or down. Attack gets the full bonus; HP gets half.
In battle: +20% HP in battle
In battle: 35% chance to poison on hit (2 turns)
In battle: +15% critical hits

In battle: starts every battle with a crystal shield
In battle: your hits are never weak
In battle: heals 20% of the damage it deals
02 — Double mutation
Sometimes two mutations come together: a 2% chance, up to 5% with luck. Both count: attack, coins and sell value multiply, and the pet gets both battle bonuses.
03 — Luck
Luck makes rare mutations easier (the rarest ones go up the most). In the first 5 minutes of every hour, luck doubles for everyone, for free.
| Mutation | Normal | With ×2 luck |
|---|---|---|
| Big | 38% | 26% |
| Toxic | 24% | 22% |
| Golden | 18% | 19% |
| Crystal | 11% | 15% |
| Rainbow | 6% | 11% |
| Void | 3% | 7.2% |
04 — Sizes
Each pet is born with a size. It changes looks, weight and how much the pet earns on Guild Adventures. It changes nothing in battle.
| Size | Pet size | Adventure income |
|---|---|---|
| Mini | ×0.85 | ×0.8 |
| Normal | ×1 | ×1 |
| Large | ×1.15 | ×1.3 |
| Huge | ×1.3 | ×1.8 |
| Titan | ×1.45 | ×3 |
05 — Look rarity
Each pet has a look score (0 to 1000) from its genes: colors, pattern, glow and aura. The score sets the card’s rarity. From Legendary up, the pet is Shiny.
