For the optional Bittersweet Toast objective, follow the Pale Ravager trail and loot its body. For a general ingredient hunt, the Great Bog Wurm at Tatzelwurm's Lair is a separately reported source. Do not confuse that encounter with the quest's lizard hunt.

Follow the quest trail to the Pale Ravager

  1. Find the ritual scroll, then inspect the additional pages beyond it. The lizard note reveals the optional gland objective.
  2. Follow the slime northeast to a narrow rock opening. Squeeze through to reach the Pale Ravager's cavern.
  3. Defeat it and search the corpse. Check the gland in inventory before returning to Iulian; read the time-cost prompt when collecting it.

Resume the Bittersweet Toast walkthrough for the mixture and ritual. Finding an ingredient does not finish those stages.

Looking for an ingredient outside that quest?

All Things How reports a gland from the Great Bog Wurm at Tatzelwurm's Lair, northwest of Rock-Hollow across the river. Confirm the named map marker, approach the riverbank and search the defeated creature. This is a reported encounter, not a guarantee that every Tatzelwurm drops one.

No gland in your inventory?

Check whether you searched the corpse or only defeated the enemy. The community item database lists several loot sources and a non-guaranteed Tatzelwurm drop; these listings do not establish a universal farming route. Merchant stock and whether a purchased gland substitutes for the quest objective remain unconfirmed here. If your journal still asks for the quest creature, follow that objective rather than assuming a different ingredient source has completed it.
