Oil Elementals (D20 Modern Creature)

Created by: Dracomortis

Oil Elemental

Oil elementals spring up in places where mass quantities of crude oil are found; refineries, storage warehouses, oil spills, and the like, are all likely places for an oil elemental to come into being. Some bizarre locations have also been the site of an oil elemental creation, such as gas stations, oil transport trucks, and in at least one case, a car’s gas tank.

An oil elemental’s ink black body seems to constantly flow, and small bubbles occasionally well up and pop around its mass. It appears, coincidentally, slick and oily, and it leaves behind blobs of crude oil; although usable, it isn’t recommended, as sometimes a section of oil left behind will reanimate and attack.

Oil elementals can speak, although their speech is slurred and thick sounding, making them very difficult to understand. Weight varies depending on the size of the elemental, from 34 lbs. to over 24,000 lbs.

Species Traits

Oil elementals of all sizes have the following traits:

• Elemental: Oil elementals are immune to poison, sleep, paralysis, and stunning. They are not subject to critical hits, flanking, or the effects of massive damage. They cannot be raised from the dead.
• Caustic (Ex): An oil elemental’s slam attack deals bludgeoning damage plus acid damage from the caustic oil in its body. Creatures hitting an oil elemental with natural weapons or unarmed attacks take acid damage as though hit by the elemental’s attack.
• Flammability (Ex): An oil elemental is extremely flammable. It takes a -10 penalty on all saves made to avoid catching on fire.
• Fire Vulnerability: Oil elementals take 50% more damage when they fail a save against any fire-based attack.
