Starfury

Starfury is a sword usually found in chests on floating islands. Swinging the sword causes 3 stars to fall in exchange for a portion of your mana. The stars will pass through where your cursor is aimed. The stars also come from the corner farthest from your cursor, and because of this can not be used underground. The sword deals a base damage of 15, while the stars deal additional damage. The sword can not be swung at all when you do not have sufficient mana. This can be useful if you are trapped inside and need to attack mobs on the outside.
