Meowmere

The Meowmere is a Hardmode, post-Moon Lord autoswing melee weapon. When swung, it fires a projectile trailed by a rainbow and shaped like a cat's head, and consumes no mana or ammunition. The projectile is affected by gravity, pierces multiple enemies, and ricochets four times, dissipating on the fifth hit. The Meowmere has a 11.11% (1/9) chance to be dropped by the Moon Lord.

Tips

 * Can be very useful in close-range situations, for instance inside the Hardmode Dungeon, because of the large crowds of enemies in small chambers with relatively flat geometry.

Trivia

 * Some players are annoyed by the Meowmere's sound and choose to alter the game's sound files to remove or change it: Delete or rename  and   in the sounds folder . You may additionally copy   to both   and   so there are no missing files. The sound for   is hardly noticeable.
 * The cat-shaped rainbow projectiles are inspired by the meme.
 * Even though the Meowmere has the highest listed base damage in the game, the weapon with the second-highest base damage, the Terrarian, has higher when using the Yoyo Bag accessory. The Star Wrath also has an unlisted 2x damage multiplier on its projectiles, which technically grants it higher base damage than the Meowmere. Additionally, some single-use explosive weapons like Dynamite, Bunny Cannon, and Explosives inflict more damage than even a Ruthless Meowmere.
 * It was referred to as the Meowmur before 1.3 was released.
 * In the, one of the developers changed the game credits on to mention a supposed new melee weapon that would shoot cat projectiles, referring to the Meowmere.
