I didn't really read the adventure, just the monster combos, but it seems really... random. Demons, and then undead, and then lots and lots of cold guys.
It does make sense in the adventure; Orcus is involved.
Also, this adventure has what, 5 solos in it? It looks like a real slog. The Desecration looks like the most boring, annoying solo I've seen thusfar.
Maybe so, but encountering the Desecration only happens if the PCs fail two fairly easy skill challenges in a row. And if they do that, according to the storyline, they'll almost certainly miss the big combat involving the sorrowsworn and the angel.
Koliada's statblock doesn't designate what happens when someone is incased in Koliada's Ice. Is it a save ends condition? Are they still restrained? Etc.
They don't explicitly say it, but from the examples of other frozen victims throughout the adventure, they're completely helpless. What I wish they had mentioned, though, was how to get someone out of that state? Can you thaw them out? How long does that take? It could've used some explanation.
