Notes: Caskets can be obtained through big net fishing, drops from Dagannoths or from Treasure Trails. The Treasure Trail caskets are non tradeable and will contain your reward. Fishing or dagannoth and rock crab dropped caskets may contain a uncut gem, half keys, coins or other miscellaneous items. You can also receive them from the 'Odd One Out' random event as a reward. As of August 4, 2010 caskets are not used to carry other clues, now other clues come in a scroll box
