11Essence Arborum is a Cursed Swamps endgame resource in Windrose, harvested from plague-corrupted swamp trees by smelting plague-wood at the Smelting Furnace or Large Smelting Furnace. It is required to build the Enchanting Table (3 Mire Metal Ingot + 10 Hewn Stone + 10 Plant Fiber + 2 Essence Arborum) and to craft Ingot Arborum at the Enchanting Table itself. Stockpile 4+ Essence Arborum per Cursed Swamps trip to keep the Enchanting Table fed.22Overview55PropertyValueCategoryResourceRarityUncommonItem Level3Weight0.2Stack Size5077Acquisition88Where FoundNotesPlague-wood smeltingHarvest plague-corrupted trees in the Cursed Swamps with an axe; smelt the wood to extract Essence ArborumCursed Swamps chestsSome Ancient Ruins and dungeon chests in the swamps contain refined Essence Arborum directlyRenewable?Yes; plague-corrupted trees regrow over multiple in-game days1010Uses1111RecipeMaterialsEnchanting Table (build)3 Mire Metal Ingot + 10 Hewn Stone + 10 Plant Fiber + 2 Essence ArborumIngot Arborum (Enchanting Table)1 Mire Metal Ingot + 2 Essence Arborum + 1 Tainted BileOther endgame recipesVarious enchanted weapon and armor recipes; full list continues to be community-documented1313Farming Strategy1414Plague-corrupted trees are visually distinct: pale, twisted, with sickly bark patternsStand of plague-wood typically clusters in specific Cursed Swamps zones; mark on your mapUse a high-tier axe (Iron or Mire Metal) for fastest harvestingSmelt plague-wood at the Smelting Furnace or Large Smelting Furnace; conversion ratio continues to be community-documentedGather Tainted Bile (from Plague Crocodiles) on the same trip; both are required for the Ingot Arborum endgame chain1616Strategy1818Essence Arborum is the key Cursed Swamps resource for transitioning into the endgame.

Plan your Cursed Swamps farming runs to gather these materials in parallel rather than serially.2424Lore2626Essence Arborum (Latin for "essence of trees") is the supernatural sap that infuses plague-corrupted trees in the Cursed Swamps. The fact that plague-wood can be refined into a constructive crafting material reflects the same theme as Tainted Bile and Undead Essence: the player must turn the swamp's corruption into the means of overcoming it. Whether the trees were corrupted by the High Priestess, by older forces, or by some pact with the same dark powers that gave Blackbeard his undead fleet, is part of the swamp's unfolding mystery.2828Alternative Recipe3030At launch, the only recipe to produce Essence Arborum is the Plague Wood smelt described above (1 Plague Wood = 1 Essence Arborum at the Smelting Furnace or Large Smelting Furnace).3232IngredientQuantityTainted Maskx1Charcoalx3Duration20sResult3 Essence Arborum3434This alternative is useful after Cursed Swamps combat runs that produce surplus Tainted Masks, letting three Essence Arborum be smelted for the cost of one harder-to-replace Plague Wood.3535Complete Crafting Uses3737Essence Arborum is an ingredient in the following recipes.3939ImageRecipe OutputQuantityFabric Arborum×1Hide Arborum×1Ingot Arborum×2ConstructionBuildings, Stations, and Decorations that require this itemStationsEnchanting Tablex24141See Also4242Enchanting Table - the build targetIngot Arborum - the endgame recipe consumerMire Metal Ingot - the paired endgame resourceTainted Bile - the second Cursed Swamps endgame componentCursed Swamps - the source biome4444Tool Requirement for Plague Wood4646A stone axe will not meaningfully damage plague-corrupted trees. The trees register as a higher-tier resource, so the basic starter tool just chips at them without advancing the chop. An Iron Axe is the minimum practical tool, and a Mire Metal Axe is faster still if you already have endgame smithing online.4848This matters because Cursed Swamps trips are stamina-expensive. Chopping a plague tree with the wrong tool can leave you standing in a hostile biome long enough for respawning enemies to catch up, which is the main reason tool tier is the first thing to check before heading out.5050Smelting Fuel Note5252The Smelting Furnace needs Charcoal as fuel while it refines plague-wood into Essence Arborum. Keep a charcoal stockpile at base so the furnace is always ready to process a fresh haul without a detour through the Charcoal Kiln. A short wait for fuel is fine; an empty fuel bin that delays every endgame craft compounds across dozens of runs.5454Details5656Properties5858PropertyValueWeight0.2Stack50Discovery UnlocksEnchanted Items6060Crafted By6161IngredientQuantityCharcoalx3Tainted Maskx16363Unlocked By6464Plague Wood is the source material, harvested from plague-corrupted trees in the Cursed Swamps.
