Polarities Mod/Selfsimilar Sword

The Selfsimilar is a craftable Hardmode broadsword. A upgrade of the, it functions similarly (inflicting Chaos State on hit and dealing double damage to enemies afflicted with it) but also fires a fast-moving energy projectile with each swing. The projectile will disappear on a single hit with terrain or an enemy and does not inflict Chaos State, but still deals extra damage to afflicted foes just like the sword itself.
