Rage-Fueled Spell-casting

Prerequisites: 4th level Warlock, 4th level Barbarian, Requires a Charisma score of 15 or higher.

You've learned to channel the magic of your Pact even while in a Rage. You may cast and concentrate on certain spells albeit less effective in both power and control. The following restrictions apply to spells you cast while raging.

• You are able to cast and concentrate on spells while you are raging, but you have disadvantage on concentration checks while raging.

• If you are below 1/3 of your max health you must succeed on a Wisdom save DC of 15 or the spell fails and the attack misses. 

• The spell level you are able to cast is determined by your spell-casting class up to 4th level.
