I'm preparing to run the Neronvain portion of the adventure next. The description of the assault on Altand mentions that the dragon was backed up by a large number of masked cultists, but these cultists are not present at the dragon's lair. Did I miss a reference to where they are all supposed to be? Has anyone done anything with the missing cultists?
Also, Chuth's lair is described as a "suicidal" assault for players who try a frontal attack when the dragon is aware of them, but I can't see what makes it so hard. Dragon, dragonrider, three ettins, a bunch of 16-hp cultists who will probably not do any damage to the PCs at all and will drop with one good AoE spell ... what am I missing that will make this tough? I'd like it to challenge my players. Do I need to add more combatants? How did it work out for other groups?
Don't let the PCs sneak in quietly; mine did, talked the elf guards / cannon fodder into abandoning their posts, tricked the ettins into squabbling, then assaulted the awake Cultist squad (which woke up the sleepers) and artillery'ed the mob in a narrow hallway with our Paladin plugging the end, took on Neronvain alone (my mistake) and have only Chuth to deal with. Penny packets always lose.
Instead, whenever the PCs get into a battle - say with the ettins - have everybody else HEAR IT and call for reinforcements and come to investigate TOGETHER. Neronvain should spend 1 round checking out the situation (are your PCs
Famous Dragonslayers? how about
Famous Captors of Wyrmspeakers?) then go get Chuth ASAP.
If you have 3e sources for the Cult, use some of those cells. An L11 Necromancer Wizard should be able to AoE the PCs right back, with a tough Fighter (or paladin of Tiamat?) and some rogues to keep the PCs out of his face. Bring along a Youngling Dracolich from the MM if you think Chuth would tolerate it in his lair (my Chuth will - he's alone and needs reinforcements).
My Neronvain wears his Purple like a royal robe. A few Wearers (Othelstein, Cyanwrath) cut theirs like a military uniform; most wear nobles' garb or a purple dragonwing cape. One upcoming criminal cell leader will wear a purple pinstripe suit (he's The Godfather).
I have set up Neronvain as the usurper prince, using the Cult's criminal cells to take over turf in his father's kingdom. He expects to claim all ex-Elven kingdoms of the North as his desmense once Tiamat comes and the Cult replaces the current order. After all, he IS the rightful heir (once his older brother is dead).
Looking ahead: in 3e
Lords of Darkness, the Cult was planning to bring in an old red dragon to help protect the Well of Dragons fortress. Have the PCs fight that dragon on the way in to the Final Boss Battle.
