Oxy-Sprite (3.5e Monster)

Oxy-sprites are tiny elementals made up from concentrated oxygen drawn from the elemental plane of Air. They generally appear on the material plane in the companion of spellcasters and spelunkers who employ them as a tool or familiar.

Combat
Oxy-Sprites generally shy away from combat and are fairly weak on their own, but they are capable of making fire based effects stronger.

 : An oxy-sprite's body naturally creates a barrier to keep its core from intermixing with external atmosphere. It may expand this barrier to envelop a 5-foot square. The air barrier is too weak to divert projectile weapons, but stops any gases, fogs, mists and airborne effluvia from entering the area. Sufficiently strong winds, like from a gust of wind spell, disrupt the barrier.

 : An oxy-sprite can increase the power of nearby fire effects. Any fire effect or spell fanned by an oxysprite deals 1 extra point of damage per die. The sprite may be used as a focus by any adjacent spellcaster that it is friendly towards. Any fanned spell also gains +2 to its caster level for the purpose of duration, and +1 to its save DCs if applicable.

When used in conjunction with its air barrier, the oxy-sprite allows one Medium-sized or smaller creature to safely navigate hazardous atmospheres.

For Player Characters
