During the Trials of the Frostmaiden, the PCs have the opportunity to use resources and/or undergo effects/conditions/other mechanical events.

What isn't clear is whether players retain those conditions/changes when they return from each test.

Have I missed some guidance on this in the adventure, or is it something obvious (one way or the other!) that I'm missing.

I'm very interested in actual gameplay of one or both scenarios along with what is 'supposed to happen.' I think that the specifics of the events and consequences at an actual table would give a lot of helpful insight into this encounter and guidance for DMs.
