Sharing is caring!

What is a Crimson Worm in Pathfinder 2e? Among the most dangerous cave worms are the fiery crimson worms. In addition to being even larger than azure or purple worms, the crimson worm has a penchant for burrowing through volcanic regions that, over the generations, have infused it with a supernatural link to the Elemental Plane of Fire. The molten heart of an active volcano is an attractive lair for a crimson worm, as are the sprawling fields of bubbling magma found in the deepest reaches of the Darklands.

Crimson Worm Moats

Legends from ancient peoples, precursor dwarven societies, and colonists of the Elemental Planes populated moats of lava with crimson worms likely have some basis in truth, although the methods such ancients used to keep these “moat worms” contained and prevented them from chewing their way through fortress foundations must have been significant.


Crimson worms sometimes frequent areas on the surface where volcanism creates hot springs or other geothermal features, but even then they prefer to spend most of their time burrowing through the ground in their never-ending search for sustenance. Surface lands claimed by crimson worms are notable for the mound-shaped burrows these creatures leave behind as they dig.
