Opinions on this build.
Looks solid if you can keep your illusions up. That’s the crutch here though. To keep your damage numbers going, you need all your illusions going all the time. Ramp up takes a few seconds and cd’s can hurt ya also. Play it by ear in dungeons with swapping the bonus damage to mind wrack.
The problem with traits that apply condition upon the illusion being killed is that the application of said conditions is dependant on the target attacking and killing your illusions.
Of course NPC’s will do this (sometimes for an entire fight, completely ignoring you), but depending on your weapon choice and trait lay out, this can mean wasted traits and skill point investment. Two considerations. Either A: Replace these traits and/or better invest the skill points, or B: create a build that allows you to effectivly apply the shatter at your whim and not wait for the NPC’s actions to dictate the conditions from killed shatters.
Two things that allow you to do this are A: Sceptre’s auto attack clone spawn. Note that NPC’s tend to auto target the most recently spawned “You” (i.e the newest illusion the moment the last explodes). Or B: spawn creation on dodge roll.
If you surround your target with with clones, then sceptre and/or dodge roll create dodging over them, you can add all those stacks of conditions to the mix (without reducing your 3 active clones).
Staff is a better direct application so I don’t expect you’ll change, but it’s still condition application food for thought.
