Devoted Spirit Style

Disciples of the Devoted Spirit style are stalwart guardians trained to fight supernatural foes. Select one of the following weapons: greatclub, longsword, mace, or maul. You gain proficiency with the weapon, if you do not already have it. 

You gain 2 ki points. You regain your ki points when you finish a short or long rest.

You learn one Desert Wind maneuver of your choice, which you can perform with your selected weapon. If a maneuver you use requires your target to make a saving throw to resist the maneuver's effects, the saving throw DC equals 8 + your proficiency bonus + your Strength or Dexterity modifier (appropriate to your selected weapon).

Thicket of Blades. When a creature within 5 feet of you moves, you can spend 1 ki point and make a melee weapon attack against it.

Shield Block. When an ally within 5 feet of you is targeted by an attack, you can spend 1 ki point as a reaction to grant that ally a bonus to AC equal to your Dexterity modifier. This bonus lasts until the start of your next turn.

Righteous Vitality. Prerequisite: 7th level. When you hit an enemy, you may spend 1 ki point to regain hit points equal to your Charisma modifier.

Foehammer. Prerequisite: 10th level. Once per turn when you hit a creature with a melee weapon attack, you may spend 2 ki points and deal 3d6 extra damage. This attack ignores any damage resistance or immunity that creature might have.

Immortal Fortitude. Prerequisite: 15th level. When you take damage that would reduce you to 0 hit points, you can spend 1 ki point as a reaction. Make a death saving throw and add your Constitution modifier to the result. On a success, you stay conscious with 1 hit point.
