I feel a bit dumb now after seeing the blackflame version with delve spectres corpses doing a shit load more damage but with no investment basically. But after thinking about it id rather just not play with spectres.

The budget of this build is yes.
I dont know how far you can take it on a small amount of currency but I dont do that, i make wacky builds with stupid investment.
One mechanic I would like someone elses knowledge on is corpse life. With the current setup you can see in pob unearth spawns lvl 97 corpses and I have total 128% increased corpse life from alt quality and tree. I do not know if corpse life scaling is exponential but from poedb graphs it seems it is which brings me to 638000 corpse life for bone archers from unearth.
For defenses it is the basic aegis aurora glancing blows max block armour recovery and some life recoup, if i do get to 100 ill take the other life recoup wheel for more life recovery aswell. Also some max resists.
Also a fun note is with my current gear I can do normal alch and go maps with just shield charge and random tempest shield procs because the dmg is just that much.
