A Sound Of Thunder
Blood-crazed Battle Axe
The weapon seeks blood where it can be found, whether among the enemy or from its wielder.
This two-handed battle axe is heavy enough that you can’t wield it with one hand. The head has two blades (one on each side) and the haft is 4 feet long. When the user is bloodied, you deal +1d8 damage when you hit with this weapon.
Once a day, as a swift action, you may deal damage to yourself equal to your level, ignoring any resistances. You are considered bloodied for all purposes (including beneficial effects) until the end of your next turn.
