Crimson Briar (Patreon)

Weapon (flail) , legendary (requires attunement)

At the highest ranks of the Iron Thorn, the most worthy of the Bloody Mother's blessings wield a weapon of such cruelty and ferocity that it drives lesser beings mad at just a touch of its metal. You gain a +3 bonus to attack and damage rolls you make with this magic weapon. At the start of combat if you do not have any hit dice remaining you regain one hit die.

Grim Iron. When you damage a creature with an attack using this magic weapon, the target can't regain hit points until the start of your next turn.

Flagellate. As a bonus action you can spend a hit die to strike yourself with this weapon, imbuing the weapon with fresh pain. Until the end of your turn attacks made with this weapon deal an additional die of necrotic damage of the same type as the hit die spent.

Bloody Proliferation. As an action you can spend 4 hit dice to flourish this weapon around you and create a zone of sanguine pain as thorns of blood lash across the battlefield. You make a melee attack with this weapon against any number of creatures within 20 feet of you (even if the target is outside of the normal range of this weapon). You must roll a separate attack roll for each target.

Curse: Path of Pain. While attuned to this weapon, suffering becomes your way, your life, your very being. You regain half the amount of hit points from magical healing.

Immortality to you in her name brothers and sisters, let cry her wretched song. Go forth and malign thyself, marry iron and flesh, let bloody rivers run as the thrill consumes you. An exalted chorus we shall raise from a thousand souls, a morbid offering for our Bloody Mother to deliver us at last from this accursed cradle.
