Path of the Doom Seeker

Barbarians that travel the path of Doom believe that Death by combat is the most honourable way to die, they go into battle thinking of killing as many adversaries as possible before perishing. 

Their rage focuses only on the offensive, and each wound they take strengthens its power.

Last Stand

At 6th level, you are used to fighting near the brink of death. Whenever you would be reduced to 0 hit points , you can make a Constitution saving throw to instead be reduced to 1 hp. The DC starts at 10 and increases by 5 for each time you use this feature until the end of your next long rest.

Breakthrough

Starting at 10th level and once per rage  (while you are raging) , you can use one of your Attacks during your Attack Action to charge, using your available movent, and strike a number of enemies within range up to your proficiency bonus at the end of the charge . You must move in a straight line for this feature to be used.

You make one melee attack roll against all enemies within reach. You deal the same damage roll to all those you hit.

 

For each 10ft of your charge the attack gains +1 to hit.

All those hit by this attack must make STR saves, the DC being 8+STR+proficiency bonus, on a failure they fall prone.

After using this ability your rage ends.

Last Strike

At 14th level you are used to fighting on the brink of death, whenever you are reduced to 0 hp, you can use your reaction to strike an enemy within range, should you bring that enemy to 0Hp, you instead are reduced to 1hp.

Careless Rage

Starting at 3rd level, your rage does not give you any resistances to any type of damage nor additional damage to your damage rolls.

Instead you gain a bonus to your damage rolls equal to half the highest damage you took on a single attack roll (rounded down) while you were raging.

Reckless Cleave

Once per turn when you would use your Reckless attack feature, you can choose to attack a number of enemies in range  up to your proficiency bonus, however they can all use their reactions to make a melee attack against you provided they have enough reach.
