Nightmarish congeries of self-luminous protoplasmic bubbles, forming temporary eyes and pseudopods as necessary, shoggoths are eons-old creations of the Eld, using them both as servants and as the raw material from which they fashioned many other aberrant servitors. Fortunately, these original shoggoths -- true horrors! -- are rare, most of them having been destroyed during the turmoil that ended the Eldritch dominion over the world. The Thulians in their latter days followed in the footsteps of the Eld and created their own shoggoths and it's these creatures this entry describes. Eldritch shoggoths are vastly more powerful and would have correspondingly more impressive statistics.

Shoggoths, though amorphous, generally cover a 15-foot diameter circle and can attack opponents from any direction. Attacks that roll 4 higher than the needed number (or double the number required to hit) result in the shoggoth's enveloping its target and drawing it into its body, where it will be wholly digested in 12 rounds. Fire and electrical-based attacks do only half damage to shoggoths, as do all non-magical weapons of any sort. Shoggoths regenerate 2 hit points per round and this regeneration stops only with the creature's death; nothing else will impede it.
