Casket

A Casket is a wooden chest obtained primarily by big net fishing or killing some monsters, such as Dagannoths, and also rock crabs.

Caskets are also sometimes found during Treasure Trails after clues where you must dig somewhere. Warning: If you get a Casket in the Wilderness, do not open it there! Wait until you are out of the Wilderness to open it.

Caskets can contain any of the following items:
 * Coins
 * Gems
 * Half keys
 * Cosmic talisman
 * Chaos talisman
 * Nature talisman
