De Lurker Be'loa

This achievement requires exactly 3 players: one player on each of the two ships to interrupt casters, and one player staying behind on the docks to pull the rope. This cannot be completed with fewer people.

Have your two ship players engage the Stormwall Blockade on Normal difficulty or higher. The rope fishing pool to the left of the docks only becomes active after the boss has been engaged.

The dock player clicks the fish pool to the left of the docks. This begins a channel where the player pulls a rope out of the water and slowly gets dragged toward the water's edge.

Walk in the opposite direction from the water to resist being pulled in, but do not walk too far from the edge or the rope will break. At level 80 you take no damage during this, but falling into the water will fail the summon. Sea swells will drop on the player and must be dodged.

The two ship players must use silence and interrupt abilities on the casters aboard each ship. If a caster has a bubble around them, deal damage first before interrupting. Do not kill the casters — killing them turns them into ghosts that cannot be targeted but will continue summoning, causing the attempt to fail. At level 80, consider removing your gear or using lower-level players to avoid accidentally killing them.

The rope channel must be fully completed before the raid pushes the boss into its second phase. If the second phase begins before the channel finishes, De Lurker Be'loa despawns and the attempt fails. Coordinate with your ship players to slow or hold the boss's progress if needed.

Once De Lurker Be'loa has been summoned, defeat the Stormwall Blockade on Normal difficulty or higher to complete the achievement. You do not need to defeat De Lurker Be'loa itself.
