This build is simple ! Unleash hell on your enemies with lycath [Hunt] between red crits and cursing enemies and arcane blessing and reaper you will have roughly 90% damage reduction all the time ! They can't kill a Crit God like [Kullervo]! He wants [Revenge] for being imprisoned.....I say let's give it to him .It's a expensive build but it works!!!I can see this lasting in high endurance runs and you should have no energy issues with [Equilibrium] and lycath [Hunt] and a big enough health pool and armor to live if u forget about his puny overgaurd !!

This is Stat stick I like for him !https://overframe.gg/build/7555/lesion/melee-30-1-forma-100-status-armor-strip-viral-slash-more-will-it-blend/

Using this will alow you to hit red crits solid and you have 103% status chance absolute beast with the red crits!!! All u need is 10 seconds and u can recast ability u don't even need a target just hold it down teleport and red crits and with his 3 and a [Glaive Prime] that's impressive too!
