A few observations:
- Traps are bad. If you have a rogue or artificer in the party, let them handle it. ( I know that most groups rush through the first trap while the trapper stays behind to disarm it, but that didn't go well so and leads to...)
- Raise dead is good. Someone should either have scrolls or have it memorized. In this case, that someone should have been me, but since I solo so much, I never invested in scrolls. I now have 10. If I have to use more than 10 in a quest...ouch.
- Beholders don't live long when rushed. That doesn't mean you won't die, though (see observation above)
- Marut DR is tough! Make certain you have something that will work against it if you are melee. In my case, I had some spells and played the healer role while not blasting.
