In DragonVale for the Android and iOS systems (iPhone and iPad, etc.) the Topaz Dragon is the seventh Gemstone Dragon to be introduced in the game, representing the month of November. Being a Gemstone dragon, it earns gems instead of gold and can not mate at all.
The Topaz Dragon has a base breeding time of 30 hours, sells for 1,500,000 gold, and earns 100,000 XP upon successful breeding at level 11.
To breed a Topaz Dragon, breed a Cactus Dragon with a Firefly Dragon during the month of November. There are other dragons possible with this combination, so if you get a 30 hour incubation time then you should be on the money.
Check out my DragonVale Breeding Guide for more dragon breeding combinations, as well as the combinations you’ll need to make the necessary dragons for the Ruby Dragon, and other Gemstone Dragons.
