Mutations

Genetic mutations

The "chase the perfect roll" layer. Every creature can carry up to 4 mutations - positive buffs rolled by the server. Use a Mutagen to add one, a Helix Spinner to re-roll. Level 15+ to use.

Tiers

Each mutation rolls a tier (weighted toward Common). The tier sets the bonus size.

What a mutation can be

Stat boost (×4)

Raises one base stat - HP, ATK, DEF or SPD - by the tier's percentage.

Type hunter (×4)

Deals extra damage against a specific element: vs Grass, vs Fire, vs Water or vs Electric.

Wild Hunter

Deals extra damage against wild creatures - great for catching and farming.

Duelist Edge

Deals extra damage against trainer creatures - great for the story and bosses.

Mutagen vs Helix Spinner

Both drop from the Solroot Warden's Chest or trade on the $STKM Item Exchange. Mutations stack with forged gear, under the engine's +60% per-stat soft cap.

FAQ

How do mutations work in Soltokemons?+

Each creature can carry up to 4 genetic mutations. A Mutagen adds one random mutation to an empty slot; a Helix Spinner re-rolls all of a creature's mutations at once. Each mutation has a kind (a stat boost, a type/wild/trainer damage bonus) and a tier (Common +5%, Rare +10%, Epic +18%). The server rolls them, so they can't be grinded client-side.

How do I get mutations?+

Use a Mutagen to add one mutation to an empty slot or a Helix Spinner to re-roll every occupied slot. Both can drop from the Solroot Warden's Chest or be traded on the $STKM Item Exchange. The target creature must be level 15+.

Why can't I use my Mutagen?+

Mutations are gated to level 15 and up - the creature you target must be at least level 15. Below that, raise its level first.

Do mutations stack with gear?+

Yes - mutation and gear bonuses add together, but the engine clamps each stat channel to a +60% soft cap, so a fully mutated and geared creature stays inside the balance band. Mutations are always positive buffs.

Does a Helix Spinner remove my mutations?+

No. A Helix Spinner REPLACES each existing mutation with a fresh random one - you keep the same number of slots, just newly rolled. It never empties a slot.
