Flooded Escape from the Collapsing Tunnel

The tunnel groans around you as the last water mephits burst into spray and steam, and the mastiff's abandoned gear lies half-buried in the silt where its handlers fled. Most of the real value is portable and practical: a few useful adventuring supplies, a modest healing draught, a low-level spell scroll, and enough mixed coin and small valuables to reward a quick escape without feeling like the collapsing passage was secretly a treasure vault. Everything is damp, gritty, and in a hurry to be carried out before the next cave-in seals the route forever.
