The Red Wizard is a variant of the plain old Blue-'n'-Purple Wizard you know and love with a firey twist. He trades in his Fireball skill for a Fire Nova - dealing big damage to all enemies 'nearby' at once.
Obviously, this makes his play style much more offensive - and risky. If you protect him, he can deal BIG damage to many enemies at once (with proper positioning) ... but if he's left alone, he'll find it very difficult to survive the enemy's assault.
Keep an eye out all this week for more images of him.
