Lumenyl is a Hardmode crafting material that grows on blocks or is dropped by the enemies in the Abyss after Calamitas or Plantera has been defeated. It is used in crafting many aquatic items, typically in conjunction with Depth Cells and Tenebris.
Similarly to Crystal Shards they can also be placed on blocks and walls.
The following table displays the chances and quantities that each enemy will drop Lumenyl after Plantera or Calamitas has been defeated.
- Eidolists will drop Lumenyl only after Plantera has been defeated, unlike other Abyss enemies in which Calamitas may be defeated instead.
- After Plantera or Calamitas has been defeated, Lumenyl will begin growing on voidstone in the lower portions of the abyss being an effective way to farm large amounts of it.
- Its name was initially proposed as "Lumenite", and is still referred to as such in the mod's code. It was likely changed in-game to avoid confusion with Luminite.
