Revision 1

Essence 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.

Acquisition

Uses

Farming Strategy

• Plague-corrupted trees are visually distinct: pale, twisted, with sickly bark patterns

• Stand of plague-wood typically clusters in specific Cursed Swamps zones; mark on your map

• Use a high-tier axe (Iron or Mire Metal) for fastest harvesting

• Smelt plague-wood at the Smelting Furnace or Large Smelting Furnace; conversion ratio continues to be community-documented

• Gather Tainted Bile (from Plague Crocodiles) on the same trip; both are required for the Ingot Arborum endgame chain

Strategy

Essence Arborum is the key Cursed Swamps resource for transitioning into the endgame. Once you have:

1. 3 Mire Metal Ingot (smelted from Quagmire Powder + Ancient Scraps)

2. 10 Hewn Stone (refined from gathered Stone)

3. 10 Plant Fiber (gathered)

4. 2 Essence Arborum (smelted from plague-wood)

...you can build the Enchanting Table and unlock the Ingot Arborum recipe, which is the gateway to the highest-tier weapons and jewelry in the launch build. Plan your Cursed Swamps farming runs to gather these materials in parallel rather than serially.

Lore

Essence 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.
