White Water: The entire floor collapses into a fast-moving underground river. All characters in the area roll to grab onto a jagged ledge before tumbling in (Dex roll/Saving Throw/etc.). If they fail, characters fall into the river and are swept away. Optional: Characters might drown (Dex roll/Saving Throw/etc.). Optional: Surviving characters might end up in the next phase of the adventure.
