Path of the Sugar Rush

Not every barbarian is a warrior hardened by years of combat, some are just full of adrenaline whether its from excitement, fear or A LOT of sugar. 

Sugar Rush

While raging you no longer gain resistance to bludgeoning piercing and slashing damage. Instead whenever you are targeted for an attack you roll a D6 on a 5 or a 6 the attack misses.
additionally you can make a single melee weapon attack as a bonus action on each of your turns after this one. When your rage ends, you must make a constitution save DC 10+ half your level rounded up or suffer one level of exhaustion.

Adrenaline rush

Beginning at 6th level, you can’t be charmed or frightened while in sugar mode

Adrenaline manipulation

Beginning at 10th level, you can use an bonus action to heal yourself if you have killed a creature this turn. When you do you can heal yourself for 1d12 + your constitution modifier

Retaliation

starting at 14th level, Whenever you roll a d6 to see if the attack targeting you misses it now misses on a 4, 5 and a 6.

Additionally when an attack misses you while you are affected by sugar rush you can use your reaction to make an attack of opportunity.
