This build here but personally, swap in amalgam organ shatter and primed fury over the smite. Faction mods are inconvenient and don't do bonus damage to thrax or acolytes, but you can throw almost twice as often when adding both these mods. There's really no justification not to use amalgam organ shatter tbh.
I personally don't notice a difference between primed fury and quickening, or adding another attack speed mod on top of p fury. However, the difference just having one attack speed mod just feels amazing and gets you in a natarak like rhythm.
I'm sorry but it has to be you brother. The glaive prime is one of the strongest weapons in the entire game, and is widely accepted to be the strongest melee weapon. It might need a couple heavy detonations to kill eximus enemies but that's why i throw killing blow+amalgam organ shatter+primed fury on it for rapid throws.
Corrupt charge, primed pressure point, and fever strike, and volatile quick return are all great but you could take one off and only feel a small decrease in viability. Personally, I take off the smite. Doesn't help against acolytes or thrax and its the best spot to throw attack speed on imo.
Do start by changing your build to try and closely match the one higher in the thread. Reflex coil is a dead slot here.
