Void Essence is a Monster Loot item that drops from Shadow Brutes, Shadow Shamans, Shadow Snipers, Haunted Skulls, Serpents, and Spiders. It can also be bought from Krobus, who sells 10 per day. A Void Salmon Fish Pond can produce 5–10 Void Essence once the pond population reaches 8, making fish ponds a renewable source of the item.
Void Essence has several uses across the game. The Desert Trader accepts 200 Void Essence for the Void Ghost Pendant, but only after the player has reached 10 hearts of friendship with Krobus. It is also used at the Sewing Machine to create the Arcane Shirt, and it can be placed in dye pots as a purple dye. The dye pots for this purpose are found in Emily’s and Haley’s house at 2 Willow Lane.
The item is also relevant to quests and fish pond progression. On Winter 12, the Wizard requests Void Essence in the letter quest “A Dark Reagent,” and the reward is the recipe for Solar Essence? Actually, the quest reward is not specified in the source beyond the friendship heart reward, so only the friendship heart reward should be stated? Wait, need avoid hallucination. We have source says reward is and 1 Friendship heart, but no item. So mention only that it awards 1 Friendship heart. In addition, Void Salmon in a Fish Pond may request 5 Void Essence as part of a quest to raise the pond’s capacity from 1 to 3.
Because several late-game monsters can drop Void Essence, it is useful to keep a steady supply if you plan to buy the Void Ghost Pendant, complete fish pond requests, or craft and dye clothing. Buying it from Krobus is the most direct method when immediate access is needed, while farming Shadow enemies or maintaining a Void Salmon pond provides a renewable supply.
