Oni mage

Oni mages, often mistankenly called ogre mages, are powerful, intelligent and cunning oni that possess several potent abilities. They often stand 10-feet tall and can weigh 700 lbs. They typically lead oni and other large creatures, both as a mastermind and as a war leader; their abilities work best with allies. Oni mages are versatile giants that combine physical and magical prowess in combat, using their prodigious strength to deal out significant amounts of damage while relying on its regeneration ability to shrug off wounds. When found in real danger though, they can duck out quickly using darkness, invisibility, gaseous form, or even their ability of flight.
