Thanks. I'll post a complete build later once youtube has finished processing the videos.
Blood mage / soul blade utilizing strand of favor and cabalist's gambeson to stack focus (among many other buffs). Use Citzal's Spirit Lance for 90% of encounters, didn't memorize a single wizard spell for most of the game, eventually memorized pull of eora because it works so well at grouping enemies so the lance can get all of them. Starting stats were like 15/10/14/18/18/3, island amaua for the might resistance though wild orlan is also a good choice. Cipher spells used are mostly psychovampiric shield, borrowed instinct, secret horrors, and soul annihilation. Used minor grimoire imprint to steal various spells. Stole any wizard spell I could but the important ones were priest: (withdraw, escape, halt, and restore) and druid (nature's balm).
Important equipment: Magnera's Chain (+10 fort/reflex/will), Effigy's Husk (might immunity), ring of minor protection and prosperity's fortune (later 2x ring of minor protection), protective eothasian charm, giftbearer's cloth, bounding boots or boots of stability depending on encounter, upright captain's belt, cap of the laughingstock, squid's grasp / xoti's lantern normally used in combat before summoned weapon, weapon set 1 and 2 need lethandria's devotion and outworn buckler. This allows you to break any affliction besides dominate/charm by scripting rapid weapon switch (most important for arcane dampener). Shroud of the Phantasm to proc brilliant (though actually not necessary, can just blood sacrifice like every 10 seconds and 3 to 4 times on combat end), outworn buckler can also proc courageous but it isn't super important since we have near infinite concentration. Resounding Call for tenacious (upped later to energized with Slayer's Claw). Amra and Lord Darryn's Voulge for speed buffs. Rannig's Wrath for +10 deflection. Deltro's Cage Helm for Conduit (wearing right equipment this gives +150 to 220 or so % shock damage depending how lucky you are with the roll when chain lightning yourself). Scordeo's Trophy early to reduce recovery, later Scordeo's Edge, though you don't really need it. Sanguine Great Sword for healing. Lots of other minor equipment buffs.
I did Belranga pre-SOTP, and Concelhaut, cave grub, watershaper dragon, magma dragon, Dorudugan and HOW pre-Scordeo's Edge (also arkemyr). But I took anything that made me more powerful. This is a build that starts sorta weak but the more things you kill, the more spells you steal, and the more buffs you proc the more powerful it gets, and that applies all the way to the end, so once I got Citzal's I generally ran TOWARDS combat, I did lots of random ship encounters etc., and devoured the souls of kith and monsters everywhere.
Grimoires: Llengrath's Martial Mysteries. Aloth's Grimoire (for minor imprint). Sometimes I open with a Ninagauth's Shadowflame or Jernaugh's Equalizing burst but that is really all that's needed.
Pets: pes early on (+10% melee dmg, 5% hit to crit), bear cub once you can get him (+8 fort, 5% melee dmg), even later Ooblit (+3 sec duration all beneficial effects). Ooblit isn't really necessary but reduces how often I have to cast certain spells and abilities (escape mostly).
It's a no-rest build and I got as many buffs as I could: nature's resolve, alchemic guile/brawn/wits, cauldron shard, konstantens boon, savage cunning, hylea's bounty is best food as you can take it immediately and I think it remains the best for huge health boost, +2 all skills, +10 all defenses.
Con and especially resolve are not that important because we have huge passive healing and can enormously buff defenses with borrowed instinct, psychovampiric shield, various stolen spells and various items. Main danger to the build is certain spells like arcane dampener, though that can be cleared in a couple seconds. Form of the Helpless Beast is pretty bad. That could potentially end the run if you're hit when vela pops out of withdraw. Can actually still fight pretty effectively as the pig if she is safe because of the high attack rate, interrupts, and lightning damage. Other afflictions like paralyze don't really matter because they hardly ever hit since we have renewable inspirations up constantly for every stat besides might which is a little harder to proc, and even if you get hit with a 20 second paralyze or something you can clear it in same manner as dampener.
It is a very powerful build once it comes together around level 13 to 14. Lot of micromanagement with SOF for max effectiveness, though for party runs it would do fine without any of the SOF buffs. Can rip through bosses and waves of mooks alike.
Citzal's Spirit lance procs focus from both the primary target and secondary hits, so you build focus really quickly, and soul annihilation hits everyone the lance hits. If I were running this in a party without SOF micromanagement I would just script the char to use soul annihilation every time focus > 90 and you're threatened by more than 1 enemy, with like a 6 second cooldown. Soul annihilation was one of the things I couldn't script because the game limits the cipher resource cap to 90 in the scripting GUI, so if I want to use soul annihilation if and only if I have 1000+ focus, well, no way to do it except manually, and unfortunately with wael you're guessing at your current focus. I basically just zerged things with SA if they seemed high threat. Unfortunately SA does not generate more concentration or raise the max focus cap so you need to swap killing mooks normally with using SA on more dangerous things.
By late game in my parallel, non-iron, non-wael run I had like 15000 max focus, and you start combat with I think 1/3 of that. Or maybe 1/5...IDK, it's a lot
I was inspired toward soul blade builds from watching SarcasticSarcophagae's ultimate run where he does a soul blade / ranger, but I didn't really like the ranger aspect. I think this build is stronger but that one is easier to build focus since you can just kill your pet over and over and don't need to seek battles. But I like seeking battles. And I wanted to make a character that felt like an unstoppable kensai/mage from Baldur's Gate (or a kensai/mage/cleric...), and this is as close as I could get with POE2. Also wanted to script as much of the fighting as possible. Most encounters can be handled entirely by the script. It gets confused by things like Sigilmaster Auranic's obelisks, and you have to manually cast withdraw and soul annihilation but it can otherwise autopilot.
Hmm. Went into much more detail than I'd intended. Gotta save something for a build thread lol
