Pod

Volatile, organic pods are Heretic's version of the exploding barrel. When destroyed, they explode, dealing splash damage to anything nearby. There are also pod spawners which can create an endless supply of pods. If there is free space next to it, a pod spawner will create pods until there is no room adjacent to the spawner. The spawner will then remain inactive until the space is freed again, unless it has reached its maximum of sixteen pods.
