Path of the Savage

Path of the Savage barbarians get there abilities by bringing creatures to 0 HP. These abilities range from gaining temporary hit points, gaining immunity to certain damages, frightening the enemies and even gaining strength. 

Starved Vigor

Starting when you choose this path at 3rd level, while raging, whenever you reduce a creature to 0 hp you gain 1d6 + con modifier of temporary hit points. This increases to 2d6 at 8th level and 3d6 at 12th level.

Savage Resistance

Beginning at 6th level, while raging, when you reduce a creature to 0 hp you can choose one damage type (Bludgeoning, piercing, slashing) and you gain immunity to that damage type for rounds equal to 1 +con modifier. At 12th level you can select one element damage type (Acid, cold, fire, force, lightning, necrotic, poison, radiant, or thunder) and you gain immunity to that damage as well.

Demoralize

Beginning at 10th level, while raging, when you reduce a creature to 0 hp you may brutalize them. Doing so will cause all hostile creatures within 30 ft of you to make a will save (10 + 1/2 Barbarian lvl +str mod) or become frightened until the end of your next turn. If a frightened creature fails the save they must use their next turn to move as far away from you as possible.

 

You may use this feature a number of times per long rest equal to 1+ your proficiency modifier.

A creature who succeededs the save is unaffected by this feature for 24 hours.

 

Savage Strike

Starting at 14th level, while raging, when you reduce a creature to 0 hp you may, as a free action, make a single melee against a creature within range (You gain advantage on the attack roll). If you reduce a creature to 0 hp with this attack you gain 4 strength for the duration of your rage (You can only gain this feature 1 time per rage).
