Conquering Korthia

Find Consumption at 51.1, 41.7 in Korthia. Consumption starts as an Elite and gains stacks over time, transforming first into a Rare and then a Rare Elite — only the Rare or Rare Elite form counts toward this achievement.

Find Escaped Wilderling at 33.1, 39.5 on the west edge of Korthia. This encounter requires the Night Fae event to be active. Fight the Wilderling and then ride it, using ability 1 to tame it. Defeating it can drop Talon-Pierced Mawsworn Lockbox.

Find Fleshwing at 59.7, 43.3 in Korthia. The 'Corpse Heap' event that spawns Fleshwing requires a Necrolord character to start it. Fleshwing can drop Lord of the Corpseflies.

Head to 45.5, 54.8 in Korthia. First defeat Devouring Tear inside the nearby cave, after which Konthrogz the Obliterator spawns and patrols the road. Defeating it can drop Rampaging Mauler.

Find Blinding Shadow at 34.7, 41.9 in the Maw, located inside the Rift — a phase accessed by entering a Maw Rift in Korthia using a Repaired Riftkey, or alternatively by using a Collapsing Riftstone. Defeating it can drop Band of Blinding Shadows or Rift-Bound Shadow Piercer.

Find Deomen the Vortex at 61.3, 41.3 in the Maw. Deomen is caged inside a building at 63.3, 43.6 — to unlock the cage, activate the 2 levers located on each side of the room at the bottom, one in each alcove. Defeating it can drop Deomen's Vortex Blade or Vortex Piercing Headgear.
