Soulwrest your bread and butter, try to get a double influence one with Shaper and Hunter influence, this will help you massively with your Bound By Destiny jewel.
The Dark Monarch (Summoned Phantasms) Will double your DPS allowing you to summon more phantasms, meaning MORE added physical damage to your spells
Bonemeld Will give you a LOT of energy shield once you get all your phantasms going
Mageblood Just fixes a lot of issues
Twilight Regalia with hunter influence. I bought mine already influenced, then i spammed Essences of Woe, until I got T1 % energy shield, then I locked prefixes and reforged chaos to get the phys taken as chaos mod. Once your prefixes are good, lock them, and reforge caster to get T1 spell critical strike chance. Once you got that, for your last suffix, just go to the boat and yolo exalt, hoping for a RESIST, which you can then harvest change to fire res.
Warlock Gloves The glove slot is debatable, if you DO NOT have a watchers eye with phys converted to cold Hatred mod, you NEED physical converted to cold in your prefix and implicit, adjust this according to your budget.
Warlock Boots Fractured ES base, spam essences to get avoid being shocked with either INT or a GOOD RESIST, then boat slam your last suffix, hoping to get int or res. Once your suffixes are done, lock them, veiled chaos, unveil speed, and then you can bench craft % energy shield, or just boat slam it.
Enthalpic Ring with double influence for bound by destiny, spam essence for crit multi, res and INT, lock suffixes, reforge defense or boat slam for Energy Shield.
Cogwork Ring Ideally you want crit multi, INT, DEX, Fire Res, then for the prefixes, same as the
Enthalpic Ring.
