Encounter
Vessel of Kulemak is a repeated-defeat Abyss pinnacle encounter. After each defeat, the player can end the fight or revive the Vessel with another Lich power. Returning the Finger after three empowerments begins the full-power final phase.
How to reach Vessel of Kulemak
Use Kulemak's Invitation at the Well of Souls to enter The Black Cathedral and begin the encounter.
- Obtain Kulemak's Invitation from current Abyss endgame progression.
- Take the Invitation to the Well of Souls and use it to enter The Black Cathedral.
- Defeat the Vessel, then choose whether to take the Finger and stop or steal another Lich power and continue.
Empowerment sequence
The three available Lich powers are selected in a random order. Each revival adds one empowerment and one unrevealed Desecrated modifier to Grip of Kulemak.
- Decide before each revival whether another empowerment is worth risking the current result.
- The order of Amanamu, Kurgal, and Ulaman powers is not a player-selected sequence.
Take the Finger or continue
Taking the Finger ends the encounter at the current empowerment. Stealing a Lich's power revives and strengthens the Vessel.
- End the sequence when the current reward state matters more than the next empowerment.
- Choose Return the Finger after the third empowerment only when prepared for the full-power phase.
Full-power phase
The fourth fight adds a central Abyssal fissure, crossing portals, empowered attacks, and ground that prevents Life and Energy Shield recovery.
- Do not cross the central fissure without accounting for the following orbs and their Desecrated ground.
- Leave recovery-blocking ground immediately. Remaining on it removes the sustain needed for the next beam or cleave.
- Use the portals to cross the divided arena when the direct path is unsafe.
Cleave and beam positioning
The empowered cleave and beam reward early movement based on their wind-up rather than a late reaction at the centre of the arena.
- Read the cleave wind-up and move to the safe side before the swing completes.
- Keep a portal route available before the beam and ground effects overlap.
