Holy cow Wes...
I actually had mentioned an upgraded battle for the Cloak of Cheese in a feedback post in the other weimer mods forum, (which good Lord you put together in 2 days???), but instead you turned this city into a (albeit wonderfully fun) nightmare! My first time attacking the first group of 4 Sahuagin, I didn't buff at all and I lost a character and had barely even scratched them, so I reloaded and buffed up a bit. This time was actually WORSE as Keldorn, at the start of the fight, immediately got brought down to 4/115 hps (insane level, 3-4 hits did it) and was stunned, and I ended up losing 4 chars including the protagonist. Ok...I did get the hang of it after that and made sure I was thoroughly prepared ahead of time and started very careful planning. In case anyone else is having difficulties here, here are some observations...(and spoilers about the fights if you haven't seen them yet)
For reference, my party was PetyrBaelish (level 12/15 fighter/thief), Minsc (level 16 barbarian), Keldorn (level 15 Inquisitor), Jahiera (level 12/13 fighter/cleric), Nalia (level 15 sorceress), and Imoen (level 15 wild mage).
Do NOT let them sit back and shoot those bolts at you, as mentioned in the help file, they're highly damaging, hit at a high percentage (called shot), and of course the stunning is very bad. I recommend rushing your melee chars in there as fast as possible (Imp. haste, Boots of Speed) and having your spellcasters use party-friendly spells (Greater Malison, Slow, Holy Smite are your friends). Mordies are quite handy if you can summon them at this point. Watch out, sometimes an archer will do a loop and attack you after a break. Concentrate on one at a time, as they seem to Mass Cure upon death or at least cast it often and it'll give you more extra healing potions (you'll need 'em). Take them out in small groups at a time (usually 4), fighting 7-12 is very difficult.
As for the Priestess and the Minor Avatar of Sekolah battle, definitely concentrate on fighting the Avatar first, as the priestess/mage pretty much only uses her meteors for weapons. He sees through invisibility and I think you'll need +3 weapons or better to take him down so be prepared. The priestess is pretty tough to kill, but not much of an offensive threat...if you have the Holy Avenger or Staff of Magi at this point, hit her with that because she's got buffs up the wazoo, including Improved Mantle so you'll need a pretty good weapon to hit her anyway. Also, if at all possible, bring her down quick because her contingency is another Imp. Mantle, Stoneskin, and Heal (grrr). I was able to beat these guys the first time through, but be ready to suck down healing pots (Keldorn again at one point was down to 3 hps and still bleeding but drank it just in time, whew)...fortunately he didn't swallow any of my guys, but they bled for a while. I haven't yet fought the king and his cronies but I suspect that's going to be a real nasty fight.
In short, treat all of these guys like serious enemies, because now they are! Be prepared in every fight and try not to get spotted by multiple groups at the same time.
Wes, this is one of your best ones...you've turned what used to be a sleepwalk into a really challenging and fun series of fights. Thank you sir, you are the MAN!
