Best loot I’ve given players thus far, IMO. An untrapped, lock-free, clasp-free treasure chest containing one (1) cubic foot of pure copper and one (1) twenty-fifth of a cubic foot of sleepy baby dragon atop the copper.
Either would sell for a lot in town. Getting them back to town might prove… difficult.
A cubic foot of copper weighs about 550 pounds and would sell in the real world for $1500.
A baby dragon is a dragon also maybe mommy is around and would sell in the real world for MAX_VALUE.
