Im looking for a build to do thats going to work to the end of the game
i got a 92 trickster (soulrend/bane that barely generate enough dps)
i got a 77 slayer (flicker strike that cant survive anything)
i got a 66 marauder (didnt put the points to turn him into something)

i can reset all my passives on each character
i got 7-8 ex in budget to make something
ive checked out some guides on poe vault but i struggle getting it together by understanding how to make it good enough in my budget (i refer to their items of their build but it cost over 50 ex to get something similar)

help would be extremely appreciated on this matter
