This is the hunting setup I used at this level. You are welcome to try it for yourself but this setup may not work for everyone. Stats shown are without buffs.
This is an armor based setup and uses the exact same gear I used for level 269. I could have potentially taken the time to work out a slightly better set to better fit with the stats I need to beat, but I don't think the time is really worth the effort for such a small benefit if I have a setup that already works. Because the Quicksand Demon only has up to 25 Critical Hit, I did not worry about too many deaths.
