- 20 September 2024If a permanent with an eerie ability enters at the same time as one or more enchantments, its ability will trigger for each of those enchantments.
- 20 September 2024An ability that triggers "whenever you fully unlock a Room" triggers when a door becomes unlocked and the other door of that Room is already unlocked, or when both doors of that Room become unlocked simultaneously.
