What are the Mutations in Pew Pew Slime - Idle RPG?
Mutations are special versions of your Slime that let you evolve into stronger and more advanced forms for battle. When your Slime mutates, it transforms into a completely new character type with different looks, weapons, and fighting styles.
By advancing your Slime into a mutant form, you can boost its basic stats such as Attack, Speed, Critical Rate, Damage, and Defense. These stat boosts make your Slime much more powerful, especially during boss battles.
Each mutation also unlocks unique active and passive abilities. These abilities help your Slime perform better in fights, ThR Drm some activate automatically (passive), while others you can use during combat (active). To unlock and upgrade mutations, you’ll need to manage your coins and keep upgrading your character. As you progress, your Slime becomes stronger, faster, and more capable of winning even the toughest battles.
