Varloch and Avelyne are the twin boss encounter found within the Derelict Mansion map node on the Atlas in Path of Exile 2. This encounter draws heavily from Interlude 1: The Curse of Holten, reimagining its themes, enemies, and boss mechanics for endgame Atlas progression. While the fight itself is mechanically straightforward compared to some later Atlas bosses, understanding the map setup, attack patterns, and positioning will make the encounter far smoother.

How to Access the Derelict Mansion
To unlock the Derelict Mansion map, players must first activate Draiocht Hengestones in the surrounding connected Atlas maps. These Hengestones act as progression keys, gating access to certain nodes tied to Path of Exile 2's narrative-driven Atlas structure. Once activated, the Derelict Mansion becomes available as a destination.
On the Atlas, the map is immediately recognizable. It is shrouded in a dark, oppressive aura, with flocks of bats circling above its open spaces. This visual effect mirrors the cursed atmosphere of The Curse of Holten and serves as a warning that the area is not only hostile, but thematically steeped in decay and corruption.
Surrounding the main mansion are several smaller houses scattered across adjacent maps. Clearing or progressing around these areas is recommended, as it helps stabilize the region and provides additional experience, loot, and POE 2 Currency before tackling the boss encounter itself.
Overview of the Boss Fight
The Varloch and Avelyne fight is relatively simple in structure, especially compared to multi-phase or heavily scripted encounters elsewhere in Path of Exile 2. The difficulty lies more in managing overlapping mechanics and maintaining awareness than in executing complex strategies.
Each boss draws inspiration from earlier story encounters:
Varloch uses attack patterns very similar to Draven from Act 1, focusing on heavy melee pressure and area denial.
Avelyne is a modified version of the Asinia boss fight, incorporating spell-based control mechanics that punish players who remain stationary for too long.
Although they fight together, their abilities are distinct, and learning to recognize which boss is performing which action is key to survival.
Varloch's Attacks and How to Handle Them
Varloch is a melee-focused boss who excels at punishing players that linger too close without paying attention to his wind-ups.
Sword Slam
This is Varloch's signature attack. He slams his sword directly into the ground, creating a clearly telegraphed impact zone. Dodging the initial slam is easy, but players must remain alert for the follow-up. After the slam, a shockwave travels outward on both sides of the impact point. Many players avoid the slam only to be hit by the delayed shockwave, so it's important to dodge laterally or fully disengage from the area.
