Starfury

The Starfury is a magical sword found commonly in floating islands. When the sword is swung, 3 pinkish-red stars will fall from the sky. The damage caused by the falling stars combined with the damage of the sword itself adds up to a maximum of 45 damage per hit. It uses 11 mana per swing, allowing you to swing it for a long amount of time if you have a lot of mana. It is one of the only area effect weapons in the game. It is very useful for defeating large hoards of enemies, so it may be useful during blood moons or goblin raids. It is useful to use this sword in conjunction with meteor/cobalt armor to account for its mana cost. The stars do not penetrate blocks of any kind and as such, this weapon is severely limited when underground. Note that you cannot swing Starfury without mana.

In addition: the stars can be mildly controlled, as they willl roughly pass through where the mouse is when you click, thus you can aim higher or lower, which can be useful if you're trying to hit things over a wall. The also move from your back to your front, in a downward angle. However, you cannot use this to aim, as you will automatically turn in the direction that the pointer is from your character, even if you were facing the other way.
