Thanks man.Tested it for you. 33%. What you did was to avoid the tightest link by switching the Aura and the Iceball places in the string. Kudos.
The B12~Aura, B12 is the tightest link there.
If you add the 1 before the B12~Burst ender, it gives 34%.
So, @DarksydeDash , try playing around with
(j1/j2) b12~iceball, fjp, b12~Aura, 242, run b12~Burst and ender variations.
I think you can squeeze more damage, and still keep it practical. Essentially, adding a b12~iceball on your midscreen combo, before the aura.
