When a ? room in Slay the Spire 1 becomes an event, the game picks the event from the current act's list. Some events only appear when you meet a requirement. For the chance that a ? room is an event at all, see how the map is generated.
StS1: event or shrine
A ? room that becomes an event draws from the shrine list with a 25% chance and from the act's event list otherwise. The pick within each list is uniform, and an event you have seen is removed for the rest of the run.
The shrine list is the same in acts 1 to 3: Match and Keep!, Golden Shrine, Transmogrifier, Purifier, Upgrade Shrine and Wheel of Change. The shrine roll can also draw one-time events such as We Meet Again!, Ominous Forge, Bonfire Spirits, Duplicator, Face Trader and Lab.
