Antu'sul

Basilisk ravine
Regroup outside Antu'sul's alcove before approaching him. Keep the fight inside the cleared ravine so Earthgrab does not strand players among other packs. Pick up each summoned Servant of Antu'sul before it reaches the healer.
Antu'sul
<Overseer of Sul>Elite HumanoidAntu'sul combines summoned servants with healing and immobilizing totems, so the group must keep control of the ravine while denying his recovery.
Abilities

Antu'sul's Minion
Bring the summoned Servant of Antu'sul onto the tank and deal with its Petrify before another servant reaches the healer.

Healing Ward
Summons a ward that lasts 30 seconds. and periodically heals allies in an area around it.
Destroy the Healing Ward before it restores Antu'sul and his servants.

Earthgrab Totem
Summons an Earthgrab Totem that lasts 30 seconds. and periodically immobilizes nearby enemies.
Break the Earthgrab Totem so rooted players can move away from incoming servants.

Healing Wave of Antu'sul
Keep an interrupt for Healing Wave of Antu'sul instead of allowing him to heal while damage switches to totems.
Tank- Keep Antu'sul on the cleared ravine floor and collect his servants before they surround the healer. Call for Petrify removal when its stun prevents you from picking up a servant.
Healer- Dispel Petrify from the tank and watch for servants reaching players immobilized by Earthgrab. Keep enough distance from the alcove to see both Antu'sul's tank and newly summoned attackers.
Damage- Destroy Healing Ward on sight and release rooted players by breaking Earthgrab Totem. Keep Healing Wave interrupted while switching to the servants; killing Antu'sul does not replace finishing attackers still in the pull.
