The items which Riki can steal from an enemy are chosen from the enemy's Treasure Chest drop tables. Some enemies do not drop chests, or only drop low-grade chests, but still have a full set of wood, silver, and gold chest tables from which Riki can steal. During battle, it is possible to determine the grade of item Riki stole based on what he says: * Wood chest item: "Riki find item!" * Silver chest item: "Ooh! Riki find rare item!" or "Riki take rare item!" * Gold chest item: "Oooooh!! Rare thing!!"
