Path of the Slayer

Barbarians who walk the path of the Slayer devote themselves to an undying rage and unending battle. It is a white hot fury stoked by the desire to eradicate the evils of the world - or just ones enemies. But unlike some other paths, it is not blinding, but focused. They rage against death itself, becoming easier to revive and eventually nigh-unkillable in battle as they cut down foe after foe after foe.

Level 3: Righteous Rage

Starting when you choose this path at 3rd level, you can channel your fury into your weapon strikes. While you’re raging, the first creature you hit on each of your turns with a weapon attack takes extra damage equal to 1d6 + half your barbarian level. The extra damage is necrotic or radiant; you choose the type of damage each time you rage.

This feature has been adjusted to account for Avrae's automatic rage damage scaling.

Fury

Your Righteous Rage deals Radiant damage.

Hatred

Your Righteous Rage deals Necrotic damage.

Blessed Curse

At 3rd level, your soul is marked for endless battle. If a spell, such as raise dead, has the sole effect of restoring you to life (but not undeath), the caster doesn’t need material components to cast the spell on you.

Unstoppable Force

Once per active Rage, if you fail a saving throw, you can reroll it with a bonus equal to your Rage Damage bonus, and you must use the new roll.

Inspiring Resilience

As a Bonus Action, you unleash a battle cry infused with your own willpower. Up to ten other creatures of your choice within 60 feet of you gain Advantage on attack rolls and saving throws until the start of your next turn.

Once you use this feature, you can't use it again until you finish a Long Rest unless you expend a use of your Rage (no action required) to restore your use of it.

Undying Warrior

Beginning at 14th level, the anger and fury that fuels your rage allows you to shrug off fatal blows.

While you’re raging, having 0 hit points doesn’t knock you unconscious. You still must make death saving throws, and you suffer the normal effects of taking damage while at 0 hit points. However, if you would die due to failing death saving throws, you don’t die until your rage ends, and you die then only if you still have 0 hit points.
