Ectoplasm

Ectoplasm is a crafting material used primarily in the production of armor and weapons. It is obtained as a drop from Deep Cave Spirits found in the Deep Forest Caves, making it a mid- to late-game resource tied to underground exploration and combat.

Because it is a crafting ingredient rather than a standalone tool or consumable, Ectoplasm’s main value comes from stockpiling it for future recipes. Players venturing into Deep Forest Caves should expect to farm Deep Cave Spirits repeatedly if they want enough of it for equipment crafting. Since it comes from enemies rather than from mining or harvesting, the most efficient way to gather it is to focus on clearing areas where those spirits spawn and to keep an eye out for repeated encounters.

As with other enemy-dropped crafting materials, Ectoplasm is best treated as a progression resource: save it until you know which armor or weapons you want to make, rather than spending it immediately. Its association with combat gear means it is especially important for players preparing for tougher areas, where improved equipment makes a noticeable difference.
