Hailey, Radahn, Duala, Wenyld, and Palermo are all standing under more stable parts of the ceiling - aside from some dirt and pebbles in their hair they escape further danger.
Boulders fall around the others. Llandrin, Bilberta, Irwin, and the newly released urchin I rolled for the urchin, OM...nice meta roleplay by forgetting to roll for the poor ignored creature!


The dust settles, and the room is suddenly bright! The ceiling has given way to reveal a familiar early morning sky. The behemoth's collapse, along with the ceiling, leaves a path that can be climbed to the land above.
Meanwhile, in the room, the ice block remains unharmed. Three torches sit burning in the holders around it, with one remaining vacant. A torch remains burning in a sconce in the western wall of the half-collapsed room.
And then, chalk raises again. It scrawls across the floor. Impressive! Now free me for a great gift!
In a far corner of the room, the party sees the glint of gems laid in a well-made but dusty shield. A couple of fat pouches lay beside it.
Actions?
By the way, the party's rolls were phenomenal. The behemoth was meant to punch the ceiling each round, requiring the luck/reflex checks to be made each round. You got those bad rolls out of the way early!
