Well, we do have 250 DA shred from Pox, so that part might work out…
Whether the last one point in Aegis matters a lot I’m not sure. Worst case, you could always go back to the Serenity relic for that; Eldritch Pact should still grant more damage though.
But effectively it still translates to DA for us, right? I think I once ran a Demonslayer WH with like 2750 DA back in the olden days (AoM), and that one worked just fine (it also had another 130 OA shred from Veil of Shadow & a f*ckton of life leech, but considering the circumstances this shouldn’t be too different).
I think, however, that we are now at a stage where further progress can only be made via actual playtesting anyways…
