"Shrieks are echoing from the dungeon."
A Phantom Spirit is a post-Moon Lord flying enemy that spawns in the Dungeon after Moon Lord has been defeated. Similarly to a Dungeon Spirit, it has a chance to spawn after defeating certain enemies and can fly through walls. It drops Phantoplasm, an end-game crafting material used mostly for crafting post-Devourer of Gods items. After killing thirty Phantom Spirits, Polterghast will spawn if it has not yet been defeated in the current world.
There are multiple variants of Phantom Spirits which are stronger than the normal variant, and have roughly a 20% chance to spawn in place of one. The Happy Spirit has the largest damage and health, followed by the Angry Spirit and then the Sad Spirit.
The Happy Spirit is uniquely able to fire a fast, ghostly projectile at the player. This variant is also spawned during by Polterghast during its third phase.
- It is possible for both a Phantom Spirit and a Dungeon Spirit to spawn at the same time when killing an enemy, and it is also possible for a Phantom Spirit to spawn after killing a Dungeon Spirit and vice versa.
