There’s a few skill rotations depending on what your fighting, but if your just trying to kill someone quick i’ll usually start with my greatsword and toss out an illusionary berserker(4) then hit em with an illusionary wave(5) to interrupt and stun them for the next attack. I then switch weapons, hit them with and magic bullet (5) to stun them, then cast illusionary duelist(4), then illusionary leap(3) to immobilize them, then a blurred frenzy(2), I’ll use mind wrack(f1) while i’m in blurred frenzy, then cast decoy(8) and mirror image(7) and hit them with cry of frustration (f2). If they’re not dead yet, then switch back to greatsword, cast another illusionary berserker, and maybe blink(9) away if u need space. If I need to get away, I can just dodge, switch weapons, dodge then cast distortion (f4) and I’ll be able to cast mass invisibility (0) and run.
