Enchanted Sword (NPC)

The Enchanted Sword is a Hardmode enemy that spawns in the Underground Hallow. It hovers and spins before flying at the player, traveling through blocks. Any knockback stops its attack, forcing it to pause and spin up again. It can inflict the Cursed debuff.

Trivia

 * The Enchanted Sword's appearance is the same as Excalibur, except for the blue glow.
 * Most likely a tribute to Castlevania, where swords and hammers have the same attack pattern.
