Exodia Force : On Status Effect 50% chance to deal 200% Weapon Damage to enemies within 6m.

I didn't intend to make this build public but it works pretty well and you may found some ideas here.

My goal was to build a melee weapon to effortless (aka spam) kill eximus/boss without sacrificing my trash mob bashing capability. High crit base ensure to fast kill low mobs who won't live enough time to be statued. Status chance ramps up easily with attack speed to grow numbers against tougher mobs. If you don't need corrosive you can use smite mods instead of [Shocking Touch] for better results. [Bleeding Willow] is the highest DPS stance mod you can get for polearm with à fluid animation to spam.
Use whatever you want on arcane slot, i put this exodia force to have larger AoE and more kills to trigger more easily "on kill" mechanics

Overall this build does the job i expected, i get my MR 30 and Arbitration defense 60 waves with it on a wukong tank, also viable for some Steel Path missions.

For further improvement or riven mod, keep in mind :
-Status chance and attack speed will brings your damage faster but not higher (or too few)
-Crit chance is already high it won't give you much, on the other hand crit damage is a good spot to work on
-Initial combo and melee damage are good too if you seek riven mod
-Range is good if you are farming large packs and boss but you have too lowered your damage
-Smite mods are very good and too often underestimated but require [Preparation] and turn your build into a more situational one

Have fun !
