[S4] Necro Bone Spear

I can’t seem to farm comfortably using this build on pit89.
Currently at Lv90 but with masterwork of 4/12 and 8/12. With better temperworking.

However when I use my
Barb and rogue, they can quickly breeze through pit89 even if their level is under 88-92.
Both of them are 4/12 masterworked, with good tempers.

Seems like lidless wall build is the only way for Pit farming for Necro Bone spear
