Just in case Cap of the Laughing Stock only worked with summons or duplicates, I altered my script to keep up mirror image at all times.
I STILL lost my courageous inspiration in the fight with Guardian of Ukaizo. Pretty sure wasn't from the auto rest because brilliant/energized were still up and in general time-based buffs I've extended to near infinity through cheese survive rests. Also in the video I cast psychovampiric shield but "steadfast" didn't pop up, meaning another buff was already up when cast. Think it was an attack called "Corrosive Strike" which happens at 1:26:15 and also kills Energized and Aware. I didn't see the red --Courageous-- but the next time I cast psychovampiric shield at 1:26:39 it did say "steadfast" so I had no resolve up and never saw a red --steadfast-- either. The script I wrote also keeps up psychovampiric shield at all times.
I screwed up that battle pretty badly. Closest I came in the run to dying. Only did that fight once before, because on the parallel run I forgot I had "no forced rests" mod up and the battle seemed easy, so I didn't bother practicing it. So I started with my stats lower than they were normally, no dawnstar's blessing etc or any other rest buff (didn't realize I'd been forced to rest until already started the fight), decided to let the script handle the fight and it focused mostly on the adra animats and just let the guardian attack me. Normally my defenses and healing are so high it doesn't really matter. Also should have worn Effigy's Husk. Wore Magnera's Chain which is my default because of the +10 fort/will (and reflex, but who cares about reflex). So losing Energized was bad for multiple reasons, no longer interrupted the Guardian and lost the +2 pen so was underpenetrating. Had no source of might in my hands. The "Obliterate Essence" attack apparently hits several times, and although one missed and I resisted one I still got maimed (and proned, I think).
Anyway. I eventually prevailed. Got hit with an arcane dampener during trivial fight with RDC though. Only one that hit me the whole run I think lol. My script cleared it pretty fast so was fine. Have lethandria's devotion in slot 1, outworn buckler in slot 2, squid's grasp and xoti's lantern in slot 3, script auto shuffles slot 1 and slot 2 if I lose all my inspirations at once and have no summoned weapon (which generally only happens from arcane dampener).
Would have been pretty nasty to lose an ultimate run on Ukaizo...
Pretty long run by comparison to most, 47 hours and 75 in-game days. I went out of my way to kill things and do quests I didn't have to, didn't take the best pathing etc.
Youtube still processing videos. Guess I'll submit it to Obsidian when that finishes (assuming they still veryify ultimate runs), then post a build guide. Will be my first, you've done what, like 100? lol.
Was pretty fun but kinda stressful. The worst part about an ultimate run is probably having to video everything. Worst Magran's fire challenge is Wael. Definitely Wael. I mean not the hardest but the most annoying. Can't tell how much money you have, your defenses etc., makes combat log very hard to read doing ? damage and combined with Magran almost impossible. Hardest trial is Hylea, though after you get used to taking care of Vela it isn't that bad. Woedica/Eothas combination also pretty bad, and combined with Hylea really limits class selection.
EDIT: Figured out where I lost courageous, was in the Fonferrus encounter. Lucia Rivan has some kind of aura that isn't shown in the combat log but when she walked toward me I saw the red --courageous--. I didn't notice it at the time because I was busy casting withdraw on Vela. I didn't have mirror image up yet. Lucia immediately charged me. My buff routine is pretty fast (.2 second casts, like third cast) but wasn't fast enough here. So pretty sure Cap of the Laughingstock does not apply the deflection debuff or resolve immunity unless you have some kind of duplicate up (which includes mirror image). Should maybe move mirror image to be first thing to cast, before deleterious. At least for that encounter. Alternatively if I could figure out how to script casting withdraw on vela this wouldn't happen either, but I have to do it manually which is not very efficient. I've tried casting withdraw on ally but she isn't considered an ally apparently...
AND the reason I didn't see STEADFAST when I cast psychovampiric shield in the Guardian encounter was because it missed, which is rather rare, but I had just lost nature's resolve, konstanten's boon, alchemic guile, etc.. I tried casting psychovampiric shield any time I don't have a resolve inspiration with no cooldown but sometimes it targets destructibles repeatedly and other weird behavior, plus rapidly draining focus (not that this matters this late in the game), so I put in a delay between casts. Oh well, one mystery solved. Still pretty sure Effigy's Husk does not always work but it didn't fail me in this run.
