Strand Super.
Devour Helion... you could go Devour Bleak too... but you're less mobile.
Refraction Core.
Defensive Core or Impact (Impact only buffs rank n' file dps and that's overkill, the guard endurance and resist is better for this lock kit, imo)
Hyperblade
Facet of Courage
Facet of Dominance
The artifact perk that grants bolt charge.
I'm able to hit 190 grenade (170 + font).
You can't just hold block on lock, it's a more active kit that is absolutely devasting.
All reflected shots Sever the enemies that will stack with your grenade stat boon and jolt.
You'll build bolt charge passively with regular lightning strikes going off around you every 5-15 secs depending on the ad density.
And Needlestorm hits.
Essentially free Sever buffs your buddies, your scorch, your jolt.
