Final state of starter POB: https://pobb.in/jh0LcRA70VF5
Fourth Vow higher budget POB: https://pobb.in/Y7uosmET_MxT

I leaguestarted phys crit Terminus Est Flicker Strike slayer using Abyssus + Lightning coil to counterbalance. Works great for T16s, not so much for anything more difficult due to the poor survivability. So I rebuilt to a Fourth Vow + Divine Flesh Setup, ft. Brine Crown, and it works pretty well; enough to self-level to 100 without issue, and to start clearing T17s and their bosses, although I don't think it's a great build for T17s due to having not the greatest numbers, and melee bossing often being... not the greatest of experiences POE has to offer
