Path of the Disciplined

Barbarian template

Overpower

If you miss a melee attack and the attack roll was not a 1 you can force the attack to hit. You can do this once per long rest.

At level 9 you can use this twice per long rest.

At level 15 you can use this 3 times per long rest.

Iron Will

While raging saving throws against being charmed, frightened, or unconsciousness are rolled with advantage.

You are also resistant to psychic damage. But taking psychic damage sends you into rage, if you are not already in it. This does consume a charge.

If you take psychic damage when all rages are already used, you take double damage as if you were vulnerable and do not rage. Instead take on 1 level of exhaustion. After taking 1 level of exhaustion this way you cannot do so again until the next dawn.

You are unable to become fully immune to psychic damage by any means, including spells and items.

Pummel

At 6th level if a creature within 5 feet of you casts a spell or ends its turn while concentrating on a spell, You can use your reaction to make an unarmed strike on the creature. If hit the creature's spell is not cast or if it is concentrating, it automatically loses concentration. This can be used once long rest.

At 9th level it can be used twice per long rest

At 15th level it can be used 4 times per long rest.

Cruelty

At 10th level while raging if you make a melee critical strike on a target, each consecutive melee hit on the same target by you will have damage rolled as if it were another critical. This effect will stop if you miss the target, attack another target or if the target is reduced to 0 Hit Points.

At level 17 you must miss twice in a row for the effect to stop. If target reduced to 0 Hit points or you attack another target it stops as normal.

Mortal Strike

At 14th level when you make a successful melee attack you can choose to make an unarmed attack on the same target. If this extra attack hits it does not deal damage but makes the target unable to regain hit points any way for 1 minute or until it reaches 0 hit points. This can be used 3 times per long rest.  If the attack misses it does not spend a charge.

At 17th Level this can be used 5 times per long rest.
