Magma Paraelemental Beast [Dark Sun]

Summoned only near volcanoes or wherever lava breaks the surface, this beast builds itself from the molten rock as it wells up. It resembles a baatezu: a big humanoid frame with huge clawed hands and feet, a heavy tail up to 7 feet long, and wings of running lava spanning 10 feet or more. Its skin cools nearly black but splits with every movement, showing glowing red beneath, and its eyes stay fiery red. It leaves a lava trail, and things near it tend to melt or ignite.

Its claws deal 1d6 points of damage plus 1d12 more from sheer heat. Touching it burns for 1d12 for anyone lacking protection against magical heat and flame, and flammable items it contacts, clothing included, must save vs. magical fire at -2 or ignite. It can also spit molten rock at a target within 30 feet for 4d6, halved by a save vs. spell and negated for anyone resistant to fire and heat.

The beast swims through magma at speed 15 and can use an open lava pit to hurl itself skyward and come crashing down on a foe, gaining +3 to hit, inflicting a -5 penalty on the victims' surprise rolls, and doubling its claw damage.

A mundane weapon that connects deals no harm and is consumed unless it passes a save vs. magical fire at -6. Enchanted weapons add 1 point per die of damage, but they turn red-hot and must make that same save, at no penalty, or be ruined.

Touching lava, it regenerates 1 hp each round, or 3 while submerged in an open magma pit. It is immune to heat and flame, takes double damage from cold, and loses a hit point per five gallons of water dumped on it. Water damage only regenerates inside an open pit.

Magma beasts are loners. A free-willed one usually moves into a volcano or lava field and ignores others, unless they remind it of the summoner who dragged it from home.

It has no natural role in the material world. Only if attacked without cause will it set off an eruption on purpose to hurt the creatures around it.
