Path of Magical Hatred

Barbarians who follow this path hunt down those with magic and destroy them. They may ally themselves with those of magical nature, but it generally ends poorly. These barbarians hate magic sometimes through ignorance, sometimes through rejection, and still others whose motives we have yet to uncover

Armor of Hatred

At level 3 you gain the ability to use your hatred to renove the pain your hated enemies inflict. When you are raging you have resistance to all magical damage. This effect does not cover nomagical fire, poison, ect only damage produced by a spell, a magical weapon, or a magical being such as a dragon's breath.

Know your Enemy

When to gain this class feature you are able to see all magical effects as if you had cast detect magic. These eyes of hatred are lost when you go into a rage.

You are also able to use an action to cast Dispel Magic once per rage. You are not required to have a free hand to cast it. When you cast it this way you make one attack as a part of the action. The damage dealt by this attack sets the DC for the Dispel Magic. If you are not in range to attack the item or creature you lose the use of Dispel Magic.

Spiteful Theft

Once per turn when you hit a spellcaster with a melee attack the target must roll a Constitution saving throw on a success it takes necrotic damage equal to your strength modifier, on a failure the creature loses its highest level spell slot not to exceed half your level rounded down+ your proficiency bonus. The spellcaster's hitpoint maximum is lowered by an amount equal to the spell slot lost, these hitpoints are recovered on a short rest. If the creature has no spellslots left the spellcaster automatically passes their saving throw. If the creature never had any spellslots this has no effect. If the creature hitpoint maximum is reduced to 0 the creature falls unconscious. 

Hateful Ignorance

You have trained you body and mind to resist the manipulations of magical effects. You have advantage on saving throws against magical effects and spells.
