Celestial Support Mesmer?
kitten you! I was going to post a glamour build quite like this. Although, I’m aiming for sword/pistol once the Duelist’s Discipline trait properly applies bleeding.
Some things worth noting: With 5 of stability each time you shatter, do you really need a stunbreak? Especially since you’ll be shattering often. Blinding Dissipation is also a great trait. It practically grants you invuln for an attack. DE is really key to this build, since a lot of survivability comes from shattering. I run with Adventure runes and Mirror heal/energy sigils, so my endurance is always plentiful. Bountiful Disillusionment and f2 shatters help with that too.
Damage mostly comes from conditions from staff clones and reflects. If you’re playing with a team, it might be worth it to swap out blink for portal.
Another option, if running blink, is to forego the chaos line and go into illusions for some torment/confusion damage. That probably works better for Solo-Q, but you’ll lose out on chaotic dampening, which, after this nerf, might be a worthy sacrifice.
