The build can still be improved. I'm currently in the process of farming. If Kosis doesn't die during the wave, there might be issues with the solo target, to be honest, I haven't figured out how to fix that properly yet.
I don't recommend using sacred wisps, starting from around wave 20, there's a chance that on each of them the game will just crash and you'll have 1 fps.

At the moment, what's lacking:
— I don't have any awakened gems at all. I need all possible ones at level 5.
— My chest piece lacks corruption, a new one is in progress with corruption for increased damage ㅤㅤㅤㅤand additional physical damage reduction.
— I need Enhance level 4 for the x2 effect from Sniper's Mark.
— Replace the Chaos flask with Progenesis.
— Replace the Headhunter variant with the Mageblood version.
— Level up.
— Still contemplating improving my passives tree (second cluster, possibly Thread of Hope, possibly Forbidden jewels).
— Replace my gloves with 7-link gloves for solo target (maybe).
