A Casket (elite) is received after from completing the final clue scroll of an elite clue scroll trail, and contains the reward for the trail. This is only received after either defeating a Guthix wizard or bypassing the fight using a Fetch Casket scroll with Meerkats summoned. Sometimes players will receive a Puzzle casket (elite) in its place, which requires them to complete a Celtic knot puzzle or Puzzle box before it can be opened.
