A pair built for long fights
Warlock brings a pet tank and Life Tap. Priest brings healing, shields, and Shadow Word: Pain. Together they can sustain a long route when they keep the pull count controlled.
Split the work
The Voidwalker holds the target while Warlock applies damage over time. Priest uses shields and healing as the pull requires.
On easy pulls, both players can add damage while the Voidwalker holds threat. On harder pulls, Priest should move into the healing role early.
Coordinate Fear as shared crowd control. Use it only where the fleeing target cannot add another pack.
Protect the cloth targets
Both players wear cloth. When the Voidwalker dies, the pair needs an immediate reset or crowd-control plan.
Do not use Life Tap at low health without a shield or a clear heal. An add can remove the recovery window.
Pull limits still matter
Sustain lets the pair handle the same sensible pull count for longer. Keep that pull limit when the room is crowded.
