Yo, just made a new mesmer, so if you can provide a link to best leveling build around there. Or a few so i can test around. Thanks
Mesmer leveling build
I’m no expert, but I think sword/pistol + greatsword with full zerker is pretty much the best for leveling? Summon phantasms, hit blurred frenzy, Mind Wrack when your target is almost dead. Should be able to kill any mobs quickly. As for traits, domination and dueling are pretty obvious. Maybe get Inspiration or Illusions later on for their boosts to phantasms or survivability.
