How to obtain
- Craft an Ember Charge from the Fader-to-Deep-North supply chain.
- Find petrified Gammeltroll remains in the Deep North.
- Use the charge to break the remains, collect tissue, and smelt it into Bloodgold.
What it's used for
- Smelt it in a Blast Furnace to make Bloodgold.
- Use that metal for an Intricate Key cast and later equipment.
- Carry enough charges for the deposit rather than making repeated return trips.
Common mistakes
- Treating the remains as an ordinary pickaxe deposit.
- Leaving the Blast Furnace supply chain until after collecting a key mould.
Harvesting a Gammeltroll corpse
Petrified Tissue comes from Gammeltrolls, but it does not drop like ordinary creature loot. Kill the Gammeltroll and wait for its body to petrify. A pickaxe cannot mine the resulting remains. Equip an Ember Charge, throw it at the petrified body, and collect the tissue released by the blast.
Charges connect this material to Ashlands progression. Embers come from the Eternal Pyre built with Fader's Relic, and one Ember plus two Seal Pelts makes ten charges. Carry a few on surface hunts so a Gammeltroll kill never becomes a wasted return trip.
Smelt each tissue with Coal in a Blast Furnace to receive Bloodgold. Reserve the first 15 bars for three Intricate Key casts; only then spend surplus on armor, weapons, or the Crown. Because the charge acts on the corpse, focus on winning the fight first and throw from a clear angle afterward.
Petrified Tissue and finished Bloodgold both fail the standard-portal restriction. A full stack of 30 tissue weighs 420, so place a Blast Furnace at a supplied northern outpost or plan sea transport for the ore or bars. Count tissue against the 15-bar key target and bring enough Coal so the whole batch can run without interrupting another smelter queue.
Frequently asked questions
Why will my pickaxe not mine the remains?
Gammeltroll remains require an Ember Charge after petrification; ordinary mining does not release the tissue.
What does Petrified Tissue become?
Smelt one tissue with Coal in a Blast Furnace to produce Bloodgold.
Can Petrified Tissue go through a portal?
No. Petrified Tissue is treated as ore and cannot pass through a standard portal. It weighs 14 per unit, so account for 420 carry weight when moving a full stack of 30.
