Starfury

The Starfury is a magical sword that, when swung, will send 1 pinkish-red star down from the sky. The damage caused by the falling stars combined with the damage of the sword itself adds up to a maximum of 60 damage per hit (inaccurate information as of 1.2. Starfury was slightly tweaked). It is one of the only area effect weapons in the game.

The Starfury is very useful for defeating large hordes of enemies, thus making it useful during Blood Moons or Goblin Invasions. It is useful to use this sword in conjunction with Meteor Armor or Jungle Armor to account for its mana cost.

In 1.0.5, the stars did not penetrate blocks of any kind and as such, this weapon was severely limited when underground. As of update 1.0.6, stars will hit enemies in caves. The stars will go through walls until they hit an enemy or a material after passing through an open space. You cannot swing Starfury without mana.
