Path of Woad

The night before a battle, Woad Warriors would dance around fires and walk through hot coals to prove their immunity to pain. The day of the battle, they imbibed from an enemy's skull an elixir of war, the ingredients of which have been lost in the mists of time. They then danced around, bit their shields, and screamed and bellowed at each other. At the height of their frenzy, they charged headlong towards the enemy, bearing spiked shields, with no regard to pain, injury, or death. Many enemies fled merely at the sight of the crazed horde of naked fanatics charging towards them.

Instil Fear

Beginning at 10th level, you can use your bonus action to inflict a wound upon yourself.

When you do so, choose one creature that you can see within 30 feet of you. If the creature can see or hear you, it must succeed on a Wisdom saving throw (DC equal to 8 + your proficiency bonus + your Charisma modifier) or be frightened of you until the end of your next turn. On subsequent turns, you can use your action to extend the duration of this effect on the frightened creature until the end of your next turn. This effect ends if the creature ends its turn out of line of sight or more than 60 feet away from you.

If the creature succeeds on its saving throw, you can’t use this feature on that creature again for 24 hours.

Blow for Blow

Starting at 14th 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.
