Base Class: Wizard
Battle Mages blend defensive and offensive magic to combat their enemies, hurling magical energy and shielding themselves from harm. They view magic as both the best weapon and the best armor, wielding it to become a master of combat. Unlike other wizards, Battle Mages fight on the front lines, blasting their foes at a point-blank range.

Level 3: Point-Blank Blast

When you cast a spell that deals damage and expends a spell slot, you can expend an extra spell slot of 1st level or higher to deal extra damage equal to 5 × the level of spell slot expended.
