From the Rethramis Continent portal, head up Lost Ark Gold past the Temporary Encampment to the Burnt Encampment. Follow the southern edge of the area as it heads east and you should come across the Boss Mungka. If you get to the southeast point where the path thins, you’ve gone too far.
Boss Paingolin Monster Location – North Saland Hill
Head east from Nomad camp and then south east through this large area. Keep near the eastern edge and walk back-and-forth north and south between the east and south exits of this area. You’ll soon come across a Boss Paingolin mixed in with the saltbugs and mungka. While you’re here, be sure to keep an eye out for the "Salt-grilled Saltbug" tome ingredient that’s also in this location.
Dirty Mucus Lump Monster Location – Sapira Cave
Work through the first part of Sapira Cave and slide down the slope. When you get to the point here where you fight the second and third Enhanced Wormfists, the second one will be grouped with the Dirty Mucus Lump. Hint: Where you defeat it, you’ll also find the "Hidden Encavian Liquor Bottle" ingredient needed for the Age-old Encavian Wine recipe.
Dirty Salt Worm Monster Location – North Saland Hill
Leave the Nomad Camp by the east exit and head into the northern salt plain by the eastern one of the two northern passageways. Head right into the eastern corner Lost Ark Gold for sale, where you’ll find a group of salt worms – one of which will be the Dirty Salt Worm. Note: Right where he spawns, you’ll also find the "Salt Worm Poop" ingredient for Worm Poop Coffee, one of Yudia’s Adventurer’s Tome recipes.
