Ectoplasm

Ectoplasms are a hardmode endgame material. It drops in Dungeon by defeating a Dungeon Spirit. Dungeon Spirits release 1-3 Ectoplasm upon death. It is used to craft the Spectre armor and tools. To craft all Spectre equipment including the wings in the PC version the player needs to acquire 115 Ectoplasm.

Tips

 * Due to the difficulty of the Dungeon in hardmode, Hallowed Armor or similar is recommended to collect them.
 * As an end-game set, it may require many trips to a Dungeon to complete it.
 * If your Dungeon is shaped so you can safely fire down at enemies then ectoplasm can be hoarded early, thus eliminating the need for getting adamantite.
 * Ectoplasm is a very good source of cash, as each piece of ectoplasm is worth, and it is easy to get with a full set of Spectre Armor and a Shadowbeam Staff, as you will get healed for each hit, plus you can get Ectoplasm easily in large hordes.
