Ectoplasm is a Hardmode post-Plantera material dropped from the Dungeon Spirit in the Dungeon. Dungeon Spirits drop 1-3 Ectoplasm upon death. It is used by Console, Mobile, and players to directly craft the Spectre armor and tools. On the Desktop version, players use Ectoplasm to craft Spectre Bars, which in turn are used to craft Spectre armor and tools.
On the Console version, Mobile version, and version, the player needs to acquire 136 Ectoplasm and 126 Chlorophyte Bars to craft all Spectre equipment including the tools, wings, armor and both forms of headgear. For all just the components of the Spectre armor set (including both forms of headgear), the player will need 66 Ectoplasm.
- Due to the difficulty of the Dungeon in hardmode, Hallowed Armor or higher is recommended when farming Ectoplasm. It may take multiple trips to acquire enough for all items.
- Ectoplasm is a very good source of cash, as each piece of ectoplasm is worth 50 .
- If you have enough spare Souls of Flight, it may be desirable to craft Ghost Wings instead of simply selling the ectoplasm, as each set of wings is worth 8 , while the components are worth 5 40 . If you're lucky, the wings might even get a modifier, making them sell for more. (Console/Mobile only, as Spectre Wings' components will sell for 10 40 )
- Ectoplasm is a fictitious ethereal substance appearing in games, movies, and books that ghosts, phantoms, and other entities leave in the mortal realm, usually when destroyed.
