I'm DMing the last leg of Reign of Winter. My PCs are in section A6 of the Witch Queen's Revenge and just killed the summoned bone devils. The ice devils that summoned them, who work for Elvanna, watched the fight and decided they did not want any part of fighting the PCs. The party's Chelaxian wizard had tried to make a deal with the summoned minions, so the ice devils knew she would be amenable to it. And what ice devil can resist such machinations with a high-level party when they come calling?
The ice devils wanted a trade for services rather than material possessions. The other party members were like, whatever, I just like killing your kind, and the ice devils were like, cool, that could be arranged. They offered the name of a devil and a gate and said they would allow the PCs to pass unhindered if they brought proof of killing him. The PCs said, yeah, why not? This was all spur of the moment, and I had nothing prepared.
Soooo.... I need an adventure.
My first thought is to teleport them into a modified extraplanar Witchwar Legacy. Does anybody know any good 16th-level one-shots? I'm also looking for a place to insert the "antiparty" trope in these last few game sessions.
Any thoughts?
If I recall correctly they encourage you to maybe have Vsevolod's return.
If Vsevold is slain, perhaps his patron Kostchtchie claims his soul and reworks him into a truly horrific Abyssal monster -- possibly a demonic Svathurim with extra legs, oversized clawed hands, and a monstrous head -- who reappears sometime later in the AP to wreck havoc on the characters who killed him.
After re-reading it, I'm down for the Witchwar Legacy. It's a compelling high-level dungeon with fun traps, puzzles, fights, and Baba Yaga lore. It even has a Cornugon devil, which is the type of devil the Ice devils wanted to kill. I'll shave off a few of the filler fights, maybe swap the Cornugon into the final guardian position (to avoid another high-level witch fight going into fighting Elvanna), and give him another template or two.
I can insert the antiparty somewhere into the Cottage or the Kurgan. I would also be on the lookout for a few high level traps or puzzles to add to those areas.
I meant to mention Vsevolod in there. He did manage to kill a PC, so maybe they would remember him if I stuck him in there as a vengeance run for Kostichie's followers.
