Obsidian Elemental

About

This creature is a powerfully built, roughly humanoid-shaped monolith of black stone. Its hands end in wicked, serrated and jagged claws. No facial features can be discerned.

In a realm where elemental water and elemental fire conjoin, there exists a pocket plane known as the Plane of Obsidian; a plane of barren wastes and blackened rock, of razor-sharp obelisks and fields of sharpened glass. Creatures native to this plane appear as blackened obsidian with jagged, serrated, or clear-cut angles and edges. Some have barbed spikes adorning their elemental forms.

Obsidian elementals are usually encountered on their home plane or on the Plane of Fire. Still, some can be found on the Obsidian Plain in the Plane of Molten Skies (see the City of Brass by Necromancer Games).

Most, however, prefer the serenity that the Plane of Obsidian offers, and thus they rarely venture forth unless summoned.

Obsidian elementals are deadly combatants and strike with their sharpened claws, ripping and tearing at their opponents. They are relentless in their attacks and never give quarter.
