Blood oath

Blood oath is a melee sword dropped by moon lord. It has no projectiles, but to compensate, swings extremely fast, and does 30 damage. When it hits an enemy, there is a 10% chance of it healing the player by 3% their current hp.

TRIVIA
Blood oath has blood dripping from it.

The 2 'pipe' objects are extra blades.
