Looking for help designing one final session: Cryovain's revenge!
​
Hi all! Some of you may remember my post from last week about potentially scrapping my campaign after my brother's wife joined the group. I really appreciated all the advice and different perspectives people offered.
Ultimately, I decided that the best option is to run one final session, get the party safely to Neverwinter, and leave the campaign there. I've been getting a little burnt out anyway, and honestly, this seems like a good opportunity to hand the DM reins over to my brother for a while. He can deal with his wife as the DM.
What I'm actually looking for help with today is putting together that final session.
The party is currently traveling toward Neverwinter. They were originally heading there having dealt with some bandits then collecting their reward in the city. I've already been considering bringing back Cryovain, the white dragon they've encountered once before. The first time they fought him, they absolutely demolished him, and he barely managed to escape. So naturally, I think some revenge is in order.
The important part is that I need this to be a SINGLE session, probably around 4 hours. There won't be much social interaction, so I'm thinking I can make it fairly combat-heavy and essentially give them a full adventuring day's worth of encounters.
My rough idea is:
Fight 1: Something relatively straightforward to start draining some resources.
Fight 2: A more substantial encounter that further wears them down.
Finale: Cryovain returns for revenge and serves as the big final boss fight.
For Cryovain, I'm thinking about using the white dragon boss from Flee, Mortals! and scaling it down to around CR 7 or 8. I really like the action-oriented boss design from that book, and I think it would make for a much more memorable final fight than just using a standard dragon stat block.
What I'm struggling with is the two encounters leading up to him. I'd love suggestions for two fights that would be challenging and interesting without overshadowing the dragon finale. Ice-themed encounters would be great, but they don't necessarily have to be related to Cryovain. I'm also perfectly happy with one or both being more generic enemies.
The party is 3 level 6(paladin,monk,wizard), and they tend to punch above their weight, so I'm not particularly worried about making the encounters a little dangerous.
If you were designing this as a one-session mini-finale, what would you put in those two encounters? Would you do a full adventuring day beforehand, or would you keep the first two fights relatively short so that Cryovain gets most of the spotlight? Any help with scaling down the stat block would also be appreciated.
Thanks!
