Special Grenade Effects

Spread the sickness. – Always corrosive. After the grenade's initial explosion, three more homing grenades are spawned. The grenades spawned will chase enemies, transferring corrosive damage on contact and then seek out another target. This will continue until the grenades disappear.

Usage & Description

The Pandemic is most useful when thrown into mobs of lesser units that are weak to corrosive damage. Such situations are common in areas heavily populated by Hyperion units, knights, and most kinds of skeletons.


  • Every time an infectious child grenade transmits a corrosive status effect to a new enemy, the grenade makes a noise like that of firing a rocket launcher.
  • The mandatory parts for the Pandemic include a corrosive accessory and a modified area effect payload called "Exterminator". The Storm Front and the Fire Bee share this part with the Pandemic, but the differences among the three are made by their Item_Balance setting.


  • Pandemic is a term used to describe a disease that spreads over a large area and/or population.
