Puzzle casket (master) is the reward from completing the final clue scroll of a master clue scroll trail, and may be received in place of a normal master reward casket. It is protected by a lockbox or tower puzzle. Once the puzzle is solved, the casket is opened and a master reward casket is received to complete the trail.

See Treasure Trails/Guide/Lockboxes and Treasure Trails/Guide/Towers for a guide to do the puzzles.
