Valeria Karinor, human skald, update 7
I found some time to play again, and Valeria entered the sewers to do the cult of the eyeless quest. First, a lich was attacked and sunrayed before being able to use his time stop. Downstairs, Aerie had a deva and some skeleton warriors take care of a beholder group. Next, Jaheira healed the demon inside Amaunator's temple.
In ghoul city, all of the undead were killed quickly, and a well protected Minsc using the iMoD +2 took on the lich group, destroying the more powerful undead due to the mace's special abilty.
Hasted skeleton warriors and Jaheira took care of some blind priests as well as the Unseeing Eye itself, plus some more beholders. Soon, Ghaal and the remaining cultists were destroyed.
Now, Valeria travelled to the temple ruins to fight the shadow dragon. A skeleton drained him of his death spell. Next, the group summoned more skeleton warriors and protected themselves with numerous buffs. The mass invisible party engaged their foe, and while Imoen was affected by his breath weapon, all of the dragon's protections were soon gone, and he died.
Imoen took care of multiple cowled wizard groups via traps - I didn't expect them to all die instantly.
Time to fight Kangaxx. The party buffed, mostly with cc, remove fear, death ward, protection from evil and mass invisibilty, and Aerie summoned a deva and some skeleton warriors to keep the lich busy. Even though the deva got stunned, the skeleton warriors managed to defeat the lich form, so Aerie cast SI:Abjuration and attacked the demi-lich with the iMoD+2. Kangaxx was destroyed immediately (I should mention that all of the protection from magic and protection from undead scrolls are gone in my installation, due to mods and the aforementioned item randomiser bug).
Valeria also decided to take on the Twisted Rune. After buffing and summoning skeleton warriors, Imoen trapped the lich, the party killed the vampire and the fighter, a deva helped with the beholder, and the mage was defeated as well.
Finally, one thing left before entering Suldanessalar - the party returned to the Underdark to finish all the encounters they previously skipped due to rushing to Spellhold and being very low level:
A well-protected group took care of the demon knights, while skeleton warriors killed some more beholders. The imprisoned souls were defeated or talked to. With some preparation and a jelly form (for safety), the first two beholders in their lair were defeated. Valeria and Aerie then summoned skeleton warriors to clear the caves, with the party helping to kill the mind flayers and a deva and an elemental prince fighting the last elder orb. A cc-buffed group entered the illithid city, fighting lots of umber hulks and mind flayers and finally defeating the elder brain.
With everything done, it was time to let Cromwell forge some final items, buy some protection from acid scrolls for Draconis in ToB and leave for the elven city.
