SRD:Efreeti

Efreeti
The efreet (singular efreeti) are genies from the Elemental Plane of Fire.

An efreeti stands about 12 feet tall and weighs about 2,000 pounds.

Efreet speak Auran, Common, Ignan, and Infernal.

Combat
Efreet love to mislead, befuddle, and confuse their foes. They do so for enjoyment as well as a battle tactic.

Change Size (Sp): Twice per day, an efreeti can magically change a creature’s size. This works just like an enlarge person or reduce person spell (the efreeti chooses when using the ability), except that the ability can work on the efreeti. A DC 13 Fortitude save negates the effect. The save DC is Charisma-based. This is the equivalent of a 2nd-level spell.

Heat (Ex): An efreeti’s red-hot body deals 1d6 points of extra fire damage whenever it hits in melee, or in each round it maintains a hold when grappling.

Spell-Like Abilities: At will—detect magic, produce flame, pyrotechnics (DC 14), scorching ray (1 ray only); 3/day—invisibility, wall of fire (DC 16); 1/day—grant up to three wishes (to nongenies only), gaseous form, permanent image (DC 18), polymorph (self only). Caster level 12th. The save DCs are Charisma-based.

Change Shape (Su): An efreeti can assume the form of any Small, Medium, or Large humanoid or giant.
