I forgot I used enlighten 3 so add +6d to the cost.
PoB - https://pobb.in/P6yVB2kryKHz
tl;dr - Tawhoa's Fellling is duplicated by triggerbots, creating 2 mirages each attack. Mirages have interesting interactions with persistent skills causing them to occur even after the mirage is long despawned. With static strike, the pulsing beams buff is placed on the ground for each mirage.
With my build, I'm able to get 10-12 static strike mirages, plus mine. They should also be doing damage from the melee strike as well but PoB total damage wont show it.
I also try to use ward as a defensive layer and it worked better than expected. Had to invest into acrobatics to make it work. Probably better and far easier to build around as block.
