Ruel's Bag - S1.E9

The group is staying at Xav's place, and getting some tips on how to deal with Grufon from its original master, Gonnard the Great. A traveling herald passes though and tells the group that kamas (gold coins) are being stolen throughout the land. Ruel, afraid his own Kamas will be stolen, retreats into his magical bag, and uses a recall potion to return home. The others, Gonnard included, follow after him. They discover his home is built into a clay mesa and has a special code to keep intruders out and keep his stash of Kamas hidden. Gonnard reveals himself to be a shapeshifting genie that turns into whatever he eats, and as he eats kamas, he's as hard as gold. He overpowers the group and eats more kamas. Ruel, not one to give up his kamas, tricks him into eating chocolate coins instead. Gonnard eats them and turns into chocolate. Ruel traps him inside a glass vase and leaves Gonnard in his vault.
