Dungeon Spirit

The Dungeon Spirit is a flying Hardmode enemy that spawns in the post-Plantera Dungeon. It can travel through walls and drops Ectoplasm, which can be used to craft many Spectre-related items.

When defeating any enemy with more than 100 maximum health in the Hardmode, post-Plantera Dungeon there is a  /  /   chance of a Dungeon Spirit spawning. On the, the enemy must also drop coins, meaning Statue-spawned and Old One's Army enemies do not spawn spirits.

Tips

 * An easy way to farm Dungeon Spirits is to find or place a Water Candle in a large room that has many tunnels leading into it and use the Piranha Gun on enemies, as the weapon will automatically chase the Dungeon Spirit when it spawns.
 * Increasing the player's luck by placing a Garden Gnome and/or drinking one of the various Luck Potions will increase the likelihood that killed enemies will spawn a Dungeon Spirit.
 * In Expert Mode, summoning King Slime in the Dungeon will provide a decent amount of Ectoplasm, as his Blue and Spiked Slimes can summon Dungeon Spirits.
 * If the player has an active Wisp in a Bottle, Dungeon Spirits may blend in and be mistaken as the Wisp, as they look very similar. Dyeing the Wisp is an effective way around this without dismissing the light pet.

Trivia

 * The Dungeon Spirit is the icon of the achievement "Robbing The Grave".
