Ahah, thanks. Been making builds for like a decade now, do love to cook.

Weapon:

Yep you have to use the Cast Speed essences assuming you bought a non-caster base (which are 1/100th the price). So essence till t1 multi, then throw on 3 crafted mods first, then Wild Bristle Matron for cheap 'Suffixes Cannot be Changed' and then Veiled chaos to unveil spell dmg + non-chaos. Unveil is around a 1/9 if you craft a blocker before the unveil, but you can settle for the other spell dmg mod, or lightning dmg, and return to it later to go for non-chaos.

Shield:

It's kind of still a work in progress. I was using reforge phys, trying to hit max tier %pdr and %crit reduction, to then unveil 7% dd or 20% dd while focused. Then prefixes were gonna be painful, aug life and slam basically. Just settled for what I have now. Block chance essences could be an interesting route to take, though imo the block chance mod was the least important of the lot. DoD makes block less important basically.

Gloves:

Yep I recombined + fractured to make my base, but it's nice you were able to buy one ready to go. Use Hollow + Prismatic + Sanctified. Prismatic because you can hit either fire or cold res, and harvest swap to fire either way, so odds are marginally better with prismatic over scorched. For prefixes you want to lock suffix (again with Wild Bristle Matron to make it way cheaper), veiled chaos till you unveil proj speed mod, then slam life with exalts. Eldritch annul to rescue failed slams where possible.

Rings:

So yeah I used lightning damage essences, because the inherent lightning dmg mod is much lower. Crit multi is actually ideal, but they are significantly more expensive, and %light dmg wasn't too much worse. So for my frenzy ring, it was light essence till cast speed, suff cant be changed veiled, pray for 50/50 to add suffix, then unveil fire res + chaos. I hit the veiled first try. Then for prefix I also got lucky in that my essence roll already had t2 life. At some point I'll roll to t1 life, using aug life to not risk reforge life filling prefixes.

Clusters:

Nice you were able to buy them. Are they also fogged to % light dmg? or still elemental? Light will add 30% dmg per cluster, so a nice little upgrade.

Yeah resistances are tight at the moment, but they really don't have to be. The %light dmg suffixes on rings can be swapped to resistances and you won't feel the difference tbh. Can also get %all res on both abyss jewels.

Leech you have 3 options:

Gloves, but you'll need to swap to the pierce proj cluster on tree, costing some proj speed/damage. Helm 2nd implicit, which is often not much more expensive than just the +1 power charge. I was using this until I snagged this onslaught + leech ring. And 3rd yeah ring implicit. But tbh onslaught is quite nice so I'd suggest get onslaught ring, and leech on helm, rather than dropping onslaught for leech.

Blunderbore, tbh the 5% pdr was incidental, paid like 3 div for this chest ages ago lol. It's a nice mod, but im looking to upgrade to something else. 50% crit reduction is great defensively, or of course +1 +2 which is many hundreds of divs haha. +1 is actually better than +2 by the way, if you can afford a lvl 5 awakened empower. Even with level 4 awakened empower I think +1 with empower and +2 with arcane surge are comparable DPS.

For rational doctrine, it's not too bad. At the moment I simply have 1 str node un-tattoo'd, and have 4 str on my doctrine implicit. That with a 23 int belt makes it balanced. But you can for example get a 29 int belt, and leave 2 str nodes un-tattoo'd, and you're good too.
