We got through Talon Pass ok. That was a fun module, but yeah it was pretty challenging. I took out all of the zombies at the beginning with my wizard, it was sweet.
It was the Kobold Hall in the back of the DMG where we got wiped out by the young white dragon at the end. We've ran a few of the Dungeon adventures and they are pretty good, much better than Keep on the Shadowfell and Pyramid of Random Encounters.
Out of interest, what level, status & composition were your party when you met the dragon down Talon Pass ?
I DM'd a party consisting of a Rogue, a Cleric, a Paladin, a Warlock and a Ranger (all 3rd level and all fully rested with full hps and powers), all played by VERY experienced players. To be honest, the dragon creamed them. At the end of the encounter (4 dead characters and the ranger legging it as fast as his little legs would carry him), the dragon still had 60+ hps remaining. I am yet to be convinced whether or not they could ever win the encounter. The killer element of the encounter turned out to be the Black Dragon's Clouk of Darkness power, which being sustainable through the use of a minor action, enabled him to take control of the whole fight by stationing it over the exit of the room and benefiting hugely from the party having no line of sight to ithe monster and it having an effective AC of 27.
The players are not happy with me, accusing me of using "a broken monster". I'd like to be able to see how other parties managed the encounter to ascertain whether the accusation is true or not.
P.S. Sorry to Joe for the discussion of a non GG adventure. If it worries you I'll stop. If it helps, the vast majority of GG adventures are much better than the one discussed above.
