Do you mind explaining why DS doesn't scale well with crit?
HL (34) + GR (15) and 26 (WL) > 62.26% effective chance
HL (34) and 26 (WL) > 51.16% effective chance
I was referring mostly to the skill Crit of the zon, which normally already gives her some ~75% crit chance, at which point the effective bonus crit chance of DS is very low.
Sure if you only have 24% from levitation mastery, then you still get a decent ratio from DS.
But then you have completely failed to understand that a bowlock deals like 1% phys dmg.
You need to build around magic dmg, or fire/magic with explosive arrows if you have a chant sorc.
Best weapon option as a standalone build:
Mist demon crossbow
Magic sunder and jewel
Best weapon option if you have a chant sorc:
Demon machine
Fire sunder and jewel
