THIS IS AN ABILITY FOCUSED BUILD
With the high strength and the buff from roar, you can get the detonations from Sow to deal 100% of enemy health as aoe damage (this means it can nuke at ANY level).
His 4 is subsumed off, so there isn't a need to mod the shadow. I might come back to modding it one day.

Playstyle:
Cast 3 to slow down enemies near you
Cast 4 to buff the damage of your nuke combo
Cast 2 to prime enemies
Cast 1 to send a shadow to wherever you are looking, used to detonate primed enemies

Archon Shards:
4 tau reds for strength
1 tau yellow for casting speed
