Evomon Natures
All 30 Evomon Natures
Filter every +10% / -10% nature, compare role priorities, and choose a reroll target without lowering the stat your build relies on.
Decision rule
Protect the build’s main stat
Choose the bonus your role uses, then make sure the penalty does not remove the HP, damage, or Speed the build needs.
Reroll
Set a target before rolling
Pick two or three acceptable natures before using potions. A usable result is often better than spending every potion on one exact name.
