The Gaudy Gem Land is an area of Botopia in Act III. It is in the southwest corner of the map, and it corresponds to Magnificus' area from Act II.
The cards Bleene's Vessel, Goranj's Vessel, Orlu's Vessel, Gembound Ripper, Gem Guardian, and Gem Detonator can be found in this area, as well as the Gemification event. The Card Choice and Card Swap events in this area have the unique property that all cards attained through them will be Gemified already. The boss of this area is The Unfinished Boss.
Upon entering this area, P03 will realize that it forgot a piece. It will unlock the Melting Room and prevent you from going further into the section until you have the piece. This piece is an attachment to the Energy bar that shows what Gems you currently have on the board. Once you have it, all your Empty Vessels will be turned into Gem Vessels.
