Scarab swarms are low levelled bug swarms that can poison, starting at 38 life points. Although their maximum hit is 20 life points, they attack extremely fast (once every game tick, or 0.6 seconds) and almost always cause damage, making them dangerous for lower levelled players. Because of the attack speed, the poison rate would be faster.
During Contact!, three swarms appear from the ground and unite to become a giant scarab. After it has been defeated, they split again and disappear.
