Guild Wars 2

How is it done? Specifically the unloaders from offhand pistol. They hit extremely hard and make it almost impossible to hit both the mesmer and the phantasm. Retalliation will destroy it in a single unload, however it will still take off around 5k hp before it finishes. Thanks for any assistance.

Put on a ranged weapon and hit the 1 skill or just use an AoE skill and blast them away. Rolling towards phantasms works wonders as they have recharge rates in between skills. If you’re up against a phantasm mesmer, you need to kill the phantasms. If you’re not up against a phantasm mesmer, you just need to dodge past the shatters or not attack during confusion/cleanse your conditions.
