Meowmere

The Meme Sword 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 C A T'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 this has the highest listed base damage in the game, the Zenith, a sword which requires the Meowmere to build, quite fittingly has much higher, even moreso with Solar Flare armor and other such accessories.
 * The Terrarian, tying with the Zenith for the second highest base damage, also 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.
 * The name may be a reference to lines from the movies Thor and Thor 2: The Dark World, where characters (usually Darcy) would regularly mispronounce 'Mjolnir' as 'Meow-mere.'
