Oni mage

Oni mages, often mistakenly called ogre mages, are powerful, intelligent and cunning Oni that possess several potent abilities.

Physical description
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.

Extra
The oni are a race of spellcasting giants. They are humanoid but often have features that set them apart from normal giants. These can include large horns, extra or missing fingers, a third eye and skin colors that range from red to blue. Given their intelligence and their magical powers, oni prefer to dress as nobility, wearing fine clothing and armor. Despite their intelligence, oni are known to be brutish and wicked. They delight in the suffering of others. They often steal what they want from surrounding communities, be it property or persons (young maidens are their favorite).
