Acid elementals appear as slow-moving clouds, ranging in color from a vibrant yellow to a dull brown. They are repellent to most force attacks, but not so resistant to elemental attacks and mental attacks.

Acid elementals generally rain or shoot acid upon opponents rolling two dice + one die for tiny, two for very small, and so forth. If a character is unlucky enough to be touched or even enveloped by an acid elemental the dice are doubled. The acid attack affects characters unlucky enough to be struck by their acid in the way outlined in the Dice Mob rules.

Water, air, or fire wielded as a weapon against them uses up one points of their mana per degree of the character wielding.
