Strategy
Portals are used to move the squad out of the attack’s area of effect, usually either Sand Swell on
Scourge or
Portal Entre on
Mesmer.
Portal Entre can be prepared outside of the radius of the attack, and should generally be opened on top of the squad or in the center of the boss’s hitbox.
Sand Swell’s range is less than the radius of the empowered attack. When the situation calls for it, the
Scourge should pre-position at the correct distance from the boss so that the portal clears the outer edge of the AoE.
Since Sand Swell is not as easily visible as
Portal Entre, it is common practice to place a marker on the
Scourge, who by positioning pre-emptively facilitates the other players’ finding the portal entrance.
