Path of Silent Wrath

A patient berserker, that truly defines rage. They can't go into a rage normally. When they get attacked they gain more rage dependent on damage, and can do more things with different amounts of rage built up.

When dealt 4 damage or lower, you get 1 rage.

When dealt 5-6 damage, you get 2 rage.

When dealt 7-10 damage, you get 3 rage.

When dealt 11-15 damage, you get 4 rage.

Any higher amounts will get you 6 rage.

Minor Frenzy

Starting at 3rd level, use 3 rage points to go into a minor frenzy. You can use one bonus attack during the whole frenzy, and you get +5 Ac and +1 strength. It lasts 3 rounds.

While in any form of frenzy, you can't be charmed, frightened, or gain any rage points.

Retalliation

Starting at 6th level, when you take damage from a creature that is within 5 feet of you, you can use your reaction to make a melee weapon attack against that creature for 1 rage point.

Mild Frenzy

Starting until 6th level, use 5 points to go into a mild frenzy for 4 turns. You have AC +6 and strength +2. You have 1 bonus attack during the whole frenzy.

High Frenzy

Final Frenzy

Starting at 14th level, use 20 rage points to go into the final frenzy. Everything within 10 feet of you is instinctually hunted down. If something isn't within 10 feet you can walk wherever you want unless a creature comes within your radius while walking. You stay frenzied for 5 turns, with a bonus attack each turn. You get +10 AC and +5 strength.

As long as a creature is within 10 feet of you, you gain an extra bonus action for the turn to attack for each. You must attack each enemy once if they are within 10 feet.
