Guild Wars 2

You can quickly strafe left and right at a distance to make Liadri’s projectiles miss you completely, in case you’re having trouble sustaining yourself in phase 1. Wells and visions always appear in the same positions relative to the first well, so memorize these locations and head toward them immediately after throwing to minimize your phase 1 time. Don’t be afraid to stand in the AoE if you need to in order to save time, and practice your dodge timing. Also, to save even more time in phase 1, you can actually pull visions into wells, and they will turn into an orb without exploding in your face if you position yourself correctly.

On the second phase, the AoE is always in an hourglass shape that alternates in a 90 degrees rotation. This means that the next safe spot will always be at 90 degrees in either direction from the previous safe spot. These safe spots are important because throwing the orb roots you for a rather significant amount of time, so you want to be in one of these when throwing in phase 2 because you cannot dodge to cancel the throwing animation.

As soon as the current AoE falls, you should approach the next safe spot (90 degrees to your left or right) that has a well in or near it, and kite/DPS Liadri while guiding the visions into the nearest well. If no well is nearby, use the opportunity to DPS Liadri instead until the AoE falls.

Once a vision has turned into an orb, pick up the orb and move to the next safe spot before throwing. When there are visions around it, use your AoE CC’s to stun/slow/push Liadri and the visions.

The only real sources of uncertainty here are the random pulls and your DPS on Liadri. There is not much you can do about the former, but with enough attempts eventually things will work out as long as you have the latter covered.
