Well that was a mess. The party cleared BG1, but what a mess of a final battle. I think I'll probably have to spend some time decompressing and thinking about everything that went wrong. Good thing Sarevok isn't an archer and so eventually a lot of distraction via various NPCs allowed charname to kill his goons and then throwing axing him to death.
LVP (Least Valuable Player) award goes to Khalid, who got injured, morale fail berserked, berserk fired an arrow of detonation at Imoen, and then died in the ensuing blast. It was doubly disappointing because he was pretty good (or at least decent) throughout the run and to have him practically sabotage the final fight just felt like a betrayal.
It also probably bears mentioning that there weren't any arrows of dispelling in my install.
The fight didn't start out great. The battle outside the temple, with the Iron Throne band, went easily so we were feeling confident. The plan had been to use our large number of fireball potions + wands of fireball + arrows of detonation to basically cheese all of Sarevok's goons with fireballs. Charname was 100% fire resistance, and others were 50-100%. That didn't really work, as I only brought two pierce magics (I didn't think there were so many casters) and one of them was wasted when it mistargeted onto Sarevok. So almost all the enemies had globes, and even after that they (presuambly due to SCS) turned into magic resistant skeletons, which fireballs also weren't effective against.
Therefore, the early part of the fight was me taking more damage than I thought would, while dealing out a lot less than I thought I would. Nevertheless, making progress and no deaths yet.
Here's where things start to go seriously wrong. Khalid gets seriously injured and fails his morale roll (a game mechanic that I sometimes forget exists). No big deal, Viconia is nearby with remove fear. Except Khalid doesn't flee he goes berserk and as mentioned fires an arrow of detonation at Imoen...
... and dies in the ensing blast. What a disaster. Meanwhile, Semaj and whoever the archer is are still globed, Angelo is invisible somewhere and even Tazok is still around.
And now things are really bad. Edwin has 33hp max, and was running at 28ish hp. A 32 damage crit from a skeleton warrior while he's off screen takes him out. Meanwhile, we are starting to run out of healing potions and there's still a lot of enemies left. It was at this point that I started to seriously worry we might lose.
Fortunately, getting everyone long-term hasted with oils of speed saves the day. Not shown, but Edwin got off a cloud kill before he died, which locked down Semaj for numerous rounds. In addition, better dodging with the various girls let charname focus on taking down Sarevok's allies. He was magic shielded (potion not scroll) so reasonably tough for anyone not Sarevok to hurt and eventually got through all the mirror images and stone skins to take everyone but Sarevok out.
Hasted Jaheira had been jogging around the room with Sarevok. He's not that hard to run away from, but he's not that easy either because he is hasted and has very low weapon speed. Anyhow, Jaheira was injured and without a source of healing and one mistake got her killed. Sarevok also hits like a truck, and a 25 damage hit was too much for her.
Losing Jaheira was bad, but fortunately she had been a good enough distraction that charname had been able to take out everyone but a few remaining skeleton warriors. Imoen replaced Jaheria in the role of distraction and charname finished off the remaining skeletons shortly thereafter.
At this point, without more healing available, we were totally unable to face Sarevok in a fair fight. He seemed to have thac0 in maybe the -5 range and hit for 20+ damage so melee wasn't going to work. Very cheesily, we therefore proceeded to throwing axe him to death over the course of 8 or 10 rounds while Imoen jogged around in a circle.
Anyhow, despite that messy battle, still pumped for a first BG1 no-reload clear and looking forward to BG2, which I am considerably less bad at (although TBD on how the throne goes if we manage to get there).
Only other comment I have is that I really wound up enjoying BG1, and enjoying it more than I thought I would. The low level D&D combat was fun and I liked how devastating any spell with a save was. It's also nice for not everything to be level 15 or a lich or a dragon (although that can be fun too).
