Monstrous centipede

Monstrous centipedes were venomous, subterranean arthropods of giant size.

Description
Monstrous centipedes ranged from halfling-size to as big as the largest dragons.

Behavior
Monstrous centipedes were adept at climbing nearly any surface with their many legs. These giant centipedes would attack anything that might be food.

Combat
When attacking, a monstrous centipede used its jaws. When it bit, it injected a poison that reduced a prey's mobility.

Ecology
Monstrous centipedes were found deep underground. They were also known to infest the Vast Swamp between Cormyr and Sembia.

History
Evil spellcasters often summoned fiendish monstrous centipedes from the Lower Planes to fight for them.
