Part Collection
Each enemy drops specific part types. Weapons from ranged enemies, armor from melee types. Farm the enemy type that drops the upgrade you currently need.
Transformation Timing
Transformations have a duration limit. Save them for boss encounters or large enemy groups where the area damage justifies the cooldown.
Upgrade Priority
Weapon damage first, then movement speed, then armor. Killing enemies faster reduces the damage you take, making armor less critical in early stages.
