er i don't know if i should tell you adrenachrome but...

you can get four frame zeal with concentrate with ith zerker, someone i used to know had one :/
you need 200% ias

it depends if you want to go full bugged out or not...

you can use 160/60 ias 40/15 ias gaze and cham storm 2x 11ll ring etc etc

its very tough to beat, but i killed his 4fps ith conc paladin that had 42% life leech 7k damage, 20% uninteruptable, 2k hp.
