what conquests did u do? i finished gr 75 and curse conquest but the other ones look incredibly hard to do
GR45 w/o sets is the easiest probably, just save some skills with insane support from items like HoTA, Multishot, WoL or something, then pick up gloves like magefist, chest like Cindercoat to increase elemental damage, rings like unity, coe, soj and its overkill. you can probably do it without too much hassle with only the skill supporting items. and dont worry if it feels slow, ofc you wont be destroying the 45 rift, it might take 10+ minutes to get it.
