Trigger The northeast bookshelf is touched
Effect Freezing mist fills a 30-foot area originating from the room's northeast corner. Creatures in the area take 5d8 cold damage (DC 25 fortitude). Creatures who fail or critically fail the saving throw take 2d8 persistent cold damage for up to 3 rounds. The affected area is filled with mist that functions as obscuring mist for 3 rounds.
Disable DC 27 thievery (expert) to deactivate the trap without its control key or DC 26 crafting to create and apply a chemical that neutralizes the gas.
Hidden jets expel gas that quickly freezes, causing limited damage to nearby books.
