Combat

Ogre mages rely on their spell-like abilities, resorting to physical combat only when necessary. When faced with obviously superior forces, they prefer to retreat in gaseous form rather than fight a losing battle. Ogre mages hold deep, abiding grudges, however, and the unwise person who crosses one would do well to keep looking over a shoulder.

Spell-Like Abilities: At will-darkness and invisibility; 1/day - charm person, cone of cold, gaseous form, and sleep. These abilities are as the spells cast by a 9th-level sorcerer (save DC 13+ spell level).

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

Flight (Su): An ogre mage can cease or resume flight as a free action. While in gaseous form it can fly at normal speed and has perfect maneuverability.

Regeneration (Ex): Ogre mages take normal damage from fire and acid.

An ogre mage that loses a limb or body part can reattach it by holding the severed member to the stump. Reattachment takes 1 minute. If the head or other vital organ is severed, it must be reattached within 10 minutes or the creature dies. Ogre mages cannot regrow lost body parts.
