PoE builds similar to 3.9 CI HoWA Cyclone Gladiator

I was inspired by some recent posts and decided to try The Hidden invitation farming strat. Expenses: I bought 15 sets of breachstones (Xoph, Esh, Tul, Uul-Netol), and a total of 5 invitations. One set of Breachstones is around 50c, an invitation is 11c. You have a pretty high chance of getting an invitation while doing a set, I got 10 The Hidden invitations as drops from Breach Bosses. I used the cheapest simple breachstones and my intention was to go as cheap and fast as possible. My total expenses were 805c or around 3.3 divs. Strat: Just run the set, kill the bosses, then run

Currently level 90. Current pob dps is about 500k. Still trying to farm atziri's step and pandemonius. Pandemonius is probably the hardest to obtain. But this was a cheap league starter, well rolled white wind was 4c and 6l i got off harvest craft. Here's the tree and gear i'm kind of aiming for, but have to wait for cluster crafting to get buffed next week.

Farmed up to T16 maps comfortably, however boss does take some time as the damage is medicore. Wanted to try something a bit different came to this. 5k hp HC LuL. Found all the gear myself except for AtzIri's step, but cost should be around here Oskarm -1c White Wind- 1c 6l Evasion- 15c Pandemonius - 55c Rest of Gear - life/resist

first time doing COC cant figure out whats wrong with my build when I'm fighting single enemies/bosses feels like im either never hitting or never hitting crits, on pob says my main hand accuracy is 100% and my crit is 100%. any help majorly appreciate.
