Revision 2

Undead Heart is a drop resource in Windrose, obtained from powerful undead enemies. The in-game flavor line describes it as a cold object that "burns your fingers," which fits the game's framing of Blackbeard's undead fleet and the Cursed Swamps plague-family enemies as supernaturally animated. Mechanically the item feeds into Cursed Swamps progression crafting and a small number of high-tier consumables.

Summary

How to Obtain

Undead Heart is not a guaranteed drop from every undead enemy. The per-kill drop rate is low on ordinary Undead mobs and climbs on elite and named variants. The reliable farming paths are:

• Cursed Swamps elites: Plague Witches, Plague Halberd-wielding corpses, and other named Plague family enemies drop Undead Heart more consistently than generic zombies.

• Blackbeard undead officers: boss encounters such as Israel Hands and elite Blackbeard Lieutenants aboard Boarding Combat targets in Blackbeard Waters list Undead Heart in the higher-rarity loot roll.

• The Cursed Swamps as a whole produce Undead Heart at roughly three to five times the rate of the Coastal Jungle and Foothills biomes, because the density of plague-family elites is much higher.

Uses

Undead Heart is an advanced crafting ingredient tied to the Cursed Swamps content layer. It appears in:

• Mire Metal Ingot variants that consume Quagmire Powder and Undead Essence. The higher-rarity Mire Metal recipes include Undead Heart as a bottleneck ingredient.

• Plague-family consumables that require a supernatural catalyst; Undead Heart substitutes for generic meat or bone components to enable the Plague-aligned effect.

• A small number of jewelry and relic recipes that ship with the Cursed Swamps content.

Farming Tips

• Target Plague Witch camps for dual farming. A single Plague Witch pull usually drops Quagmire Powder plus a chance of Undead Heart, which lets one session stockpile both of the bottleneck ingredients for Mire Metal.

• Carry Plague protection before running deep Cursed Swamps patrols. The plague accumulation rate is what cuts most farming runs short, not enemy damage.

• Undead Heart weight is low (0.1 per unit) and stacks to 40, so inventory pressure is minimal and a swamp run can return with a full stack without sacrificing other loot.
