Daves Challenge in Deathknights is pretty easy and rather small, you barely need any buffs for that one. Its an old temple with spectral dragons (level drainers).
I never got to the challenge in Pools of Darkness, as I couldnt win the final battle of the main campaign
I also didnt manage to handle the stupid maze at the end of the first Savage Frontier game (you walk from area to area on the stupid combat map, making it impossible to navigate, and run into increasingly tougher monsters with no pause for healing or rest).
The Savage frontier games were superior in one sense though, they had more unique items and weapons than the others. Krynn in particular in practice only has four or five weapon types, longsword, flail, mace, quarterstaff, and dragonlance. It offends me to have a dwarf use longsword...
