How to Get Swarmer
Swarmer is purchasable via a 799 Robux gamepass. It was originally unlocked by triumphing Eggy Island on Hard difficulty, but that method has since been removed.
Is Swarmer Worth It?
It's a budget-friendly Robux pickup with Lead detection (sting and splash only) from Level 0, useful for cheap DoT stacking on tougher enemies, though its direct DPS is modest and it never gains Hidden or Flying detection.

Best Loadouts With Swarmer
Works best alongside a strong single-hit or splash tower that benefits from Swarmer's Defense-agnostic DoT stacking on bosses and tanky enemies.
