Dungeon Spirit

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

Whenever you defeat an enemy with more than 100 health points in the Hardmode post-Plantera Dungeon there is a 8.33% (1/12) / chance of a Dungeon Spirit spawning. Statue spawned enemies will never spawn Dungeon Spirits on the.

Dungeon Spirits are immune to all debuffs except for debuffs applied from whips.

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.
 * Additionally, you can place a Garden Gnome and/or drink one of the various Luck Potions. This will increase the likelihood that killed enemies will spawn a Dungeon Spirit.

Trivia

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