The Cave of Gold is a challenge area in Skylanders: Ring of Heroes. It is a vault of riches that Golden Queen kept even more hidden than her original lair in The Golden Temple. It is guarded by Cyclopses, with some that have absorbed gold onto themselves not unlike the villainous statue and become Non-Elemental, stronger and harder to hit.
At the end of ever floor, the Doom Raider herself attacks in her giant form, using two turrets of different elements. This dungeon only allows three entries a day, possibly because the Queen can prevent further raids for a time; however, even in failed missions, the player can leave with great amounts of gold compared to regular Adventure mode.
As of December 3, 2020, the revamped version of the game removed Cave of Gold, but due to player feedback, it was reinstated three months later, with a single level and randomly generated entries. The cave's defender has infinite health, but will drop extra gold every time she's knocked down.
- The Cave of Gold, Meditation Woodland and the Guild Invasions are the only missions that cannot be entered to edit teams once the limit is over, unlike in Realm of Souls where you're allowed to enter as long as there are Skylanders with any health or recovered with Gems, or other areas when there isn't enough currency.
- In rare occasions, Golden Queen will also be extra gilded, indicating the run will wield greater amounts of treasure. This appearance comes from Skylanders: Trap Team, where unlike her normal giant form in this game, has no gems in her accessories or crown.
- In the Reboot Update, Giant Golden Queen has 7,777,777 battle points, referencing the "lucky sevens" that indicate a jackpot in gambling machines.
