Mephit

Mephits are minor creatures from the elemental planes. All mephits appear as small, winged creatures with more or less humanoid features. While they are often described as impish, their elemental origins are apparent at first glance. They are almost always true neutral.

NWN2 has fire mephits and ice mephits.

NWN Comparison

 * While NWN2 only has fire & ice mephits, NWN1 had many varieties of elemental, para-elemental, and quasi-elemental mephits. (e.g. Dust Mephits)
