Starfury

The Starfury is a Broadsword that summons a star from the sky when swung, which falls in the direction of the mouse cursor and causes damage to any enemies hit. It is one of the three rare items that can only be obtained from Skyware Chests on Floating Islands.

The sword itself deals a base damage of 22 as a melee weapon, while the stars deal an additional 22 damage and can pierce up to 2 times, which makes it quite a reliable early game weapon until you get better swords.

Tips

 * When exploring, the Starfury can be used to reveal the locations of adjoining caves because of the light it provides when colliding with blocks.
 * It is possible to use Starfury to shoot through walls by standing next to the wall and aiming towards the bottom of the screen in the direction opposite the target. Note that this is somewhat inaccurate and may not work if there are obstructions between the edge of the screen and the target.
 * In a pinch, you can also use this sword as a makeshift torch by swinging it repeatedly while underground. Useful if you're out of light sources.

Trivia

 * Originally, the starfury costed mana with each swing, and created multiple stars.
