Wow... did I seriously just talk up Demogorgon so much? I remember him being a hellish fight on Insanity, but either Core Rules is way easier or I was doing something wrong. I did some tests, and my final strategy ended up being:
-Aerie, Irwin, Imoen carry spell triggers loaded with a mixture of Breach, Lower Resistance, Pierce magic.
-Irwin and Imoen also carry contingencies with more of the same, and Aerie carries a triple wilting contingency.
-We move in with resist fear and a planetar (didn't even need any other buffs...), and Aerie and Imoen toss their spell triggers (carefully keeping Aerie at a range such that her contingency goes off after the triggers do) and Irwin and Imoen toss their contingencies while Irwin casts Improved Alacrity.
-Demogorgon punches the Planetar a bit while Keldorn, Valygar, and Viconia pretend to help.
-A few breaches get tossed at the Mariliths while Irwin lobs Horrid Wilting from his improved alacrity.
-Around three horrid wiltings later (plus the three from aerie's contingency), demogorgon dies.

Yes, you're seeing that right; an unbuffed party didn't even take noticeable damage (I think Viconia and Keldorn took one hit each from a Marilith, and nobody else took any).
Hopefully this playthrough is answering your question, ussnorway, about why I use Horrid Wilting. Honestly, at this rate it's more like Baldur's Gate 2: Throne of Horrible Wilting Abuse.
Edit:
I beat Balthazar and the Ravager to death with swords since neither are particularly threatening when compared to dragons or Demogorgon, using Abi-Dalzim's to dispel any bone swords that showed up in the latter fight. I had a lot of cheese prepared for melissan, with all 3 wish scrolls that I know of in the game (Lazarus, the Cambion in the Watcher's Keep, the final fight in the Watcher's Keep level 5) and 7 level 8 spells (and thus up to 7 potential simulacrums) plus up to 6 casts of Wish from my main character (level 9 spells); ie I was guaranteed, barring the most terrible luck in the universe, an infinite supply of wish-rests. However, it turns out it didn't prove necessary, and thus this marks the first time I've ever beaten Melissan without using a single Wish-rest!
First encounter: Ruby Ray, Breach, Whack to death.
Yan-C-Bin: Whack the Vampiric Mists to death, then the Greater Air Elementals, then the Prince himself. Planetar provides healing and restoration from level drain.
Second encounter: Whack the hive mother to death, Ruby Ray, Breach, Whack to death.
Cryomax: Whack the trolls to death, then Cryomax, then the Salamanders.
Third encounter: Wait until she summons the slayer shadows, instantly triple cast abi-dalzim's horrid wilting (which is an interesting cheese you can do with Chain Contingency: it has no cast time and doesn't count as your spell for the round--and nor does it wait if you've already cast one this round--so you can essentially exhaust a level 9 spell to instantly cast 3 level 8 or lower spells), Ruby Ray, Breach, Whack to death.
Fallen Solar: Ugh. I hate this encounter. Whack the succubi to death, Breach the mariliths, whack them to death, whack the fallen solar to death. However, that makes it sound a lot easier than it actually was (unlike the previous fights, which were all very easy). On multiple occasions Valygar, Keldorn, or Viconia were nearly dead and a planetar was charging around providing healing support. Once the first marilith went down, however, things got pretty straightforward.
Fourth encounter: Wait until she summons the slayer shadows, instantly triple-cast abi-dalzim's horrid wilting, Khelben's Warding Whip, Breach, whack, Breach, whack to death.
Enough, Amelyssan! The gods have decreed, being unkillable is tedious!

-I healed up between encounters using Superior Healing Potions (of which I had almost 100), so I was left with a huge amount of Heals just-in-case.
-I used GWW on the "boss" of each round with at least one fighter (the princes, the fallen solar, melissan).
-Valygar wielded Hindo's Doom and Yamato for this fight, since Celestial Fury's stun didn't affect... anything? Anything other than maybe the salamanders and air elementals at least, and since I was spamming GWW on any important battles belm was not necessary.
-At the end of the game, I was left with these options:
1 level 9 spell (player character)
0 level 8 spells (player character)
1 level 5 spell (player character)
A few pierce magics (all characters) and no other dispel other than on my player character
A few casts of GWW and 3 casts of hardiness per fighter
A chain contingency, elemental summoning and 3 Horrid Wiltings on Aerie.
A planetar and a... time stop? or was it improved alacrity? on Imoen, as well as one Horrid Wilting.
Two scroll cases worth of level 8 and 9 spells, notably a few (2?) scrolls of Simulacrum, 3 scrolls of Wish, 3 scrolls of Horrid Wilting, 1 scroll of Time Stop, and if I recall correctly there were also 2 scrolls of Chain Contingency. Basically I had an emergency backup wish stash in case I ran out of level 8/9 spells in a fight and still needed to wish: 9 casts of wish without a rest from scrolls alone, as well as 9 Horrid Wiltings.
Energy Blades and a Fallen Deva on Viconia.
A whole ton of resurrection, healing, healing potions, utility potions (strength, improved haste, dexterity, intelligence etc), wands, rods, protection from X scrolls, stone to flesh scrolls etc.
--
A funny thing which I forgot to mention earlier, and I guess a cautionary note about chain contingency spam, happened during the Alu-Fiend fight in level 3 of watcher's keep. Valygar was instantly charmed as the fight started, and was nuked (along with every enemy in the room) by 9 horrid wiltings. Needless to say he needed to be raised.
