Solamith

Solamiths were rare, tough tanar'ri demons that were manifestations of depraved gluttony.

Description
Solamiths were corpulent, demons that weighed up to. They had pale skin with bright green veins and horns on their head. Their most distinctive feature was the screaming faces that pressed outwards on their gut.

Abilities
Solamiths, like most demons, had darkvision; like most tanar'ri, they could attempt to summon others of their kind once each day. They were resistant to damage dealt by acid, immune to that caused by fire, electricity, and poison, but were vulnerable to the cold.

The burning hunger of solamiths charged their very flesh with a strange fire, called soulfire. Solamiths could use this is combat by tearing off pieces of their flesh and throwing it up to with perfect accuracy, causing a burst of soulfire at least  in diameter; a larger piece of flesh could cause a burst  in diameter. When a solamith took damage from a melee attack, they could also unleash a cone of soulfire in retaliation.

Behavior
Solamiths were dumb, little more than animalistic savages, and were cruel and rapacious. When eating a creature, however, they were unexpectedly dainty eaters after they'd torn the victim to pieces. When in the presence of a more powerful demon or other evil entity, they sniveled and fawned in hopes of becoming pets or prized soldiers. Unlike most demons, they were not particularly arrogant.

Combat
Solamiths preferred to use their ability to throw soulfire in combat, rarely bothering to close with opponents. Although dumb, the had a natural instinct for how best to use their soulfire bursts and cones. If forced into melee, they could attack by slamming their considerable bulk into opponents.

When seriously injured, a solamith would use the smallest soulfire burst it could, but the creatures healed at a remarkable rate. Solamiths themselves were immune to soulfire, but other creatures, even those normally immune to fire, were not.

Ecology
Solamiths were native to the Abyss, where they normally roamed either alone or in pairs. They were sometimes used in large groups as artillery units in the Blood War.

Like all demons, solamiths did not need to eat but enjoyed feeding on flesh when they could. After finishing eating a creature, a new face would appear on the solamith's gut. They did not, however, have any interest in keeping treasure.

Evil spellcasters could summon a solamith using the summon monster VIII spell, or a more powerful version.
