Phantom Spirit

The Phantom Spirit is a spooky mob found only in places such as the Graveyard, Wilderness, Spider's Den, and Obsidian Sanctuary. This mob attacks rapidly and copies the player's armor, skin, and weapon.

Trivia

 * There was a glitch where, if the player were to use a sword with the Thunderlord enchantment, the lightning strike would instantly kill the Phantom Spirit similar to dealing True Damage, ignoring all its defense.
 * When it transforms, it does not copy the player's weapon stats.
