The idea is pretty simple, but getting numbers for min maxing is hard. You cant drink soul ripper during soul gain prevention (you can drink it if you have 0 second soul gain prevention so make sure to balance it being over 0, it should be somewhat close to your attack speed, the sweet spot is unique for every character) we abuse drink when fully charged to get infinite souls, the game ques the flask up and recharges souls instantly. You need to get enough flask charges during your vaal skill duration to automate soul gains. (chalice+crits for bosses and chalice+ailments as pathfinder for maps).

If you are pro gamer you will need to sacrifice 3 flask slots for this to work (soul catcher, soul ripper and chalice) but to be safe I would recommend having 2nd soul ripper in case you spam your vaal skill while there is nothing for it to hit.

In theory this actually has better mapping potential than hateforge because you have your belt slot open.

This should work for non pathfinders if you use the heist belt but then you are sacrificing 1 more flask slot.

I try to push this build to its limits this league, which ever comes 1st me burning out or me farming hateforge to compare the 2.

Core PoB: https://pastebin.com/1PyhHWnp there is amulet with reduced duration also to mix match some things, belt isnt needed but it is also for mix matching
