How about summoning a dragon that was cast into the nether region through the portal? Now that is maximizing the useless portal decoration lol
Make commons give something useful, and I'll be happy. A twentieth of a gemstone isn't really a stretch for them to give.
I'm not sure why I don't have the option to purchase these new buildings? No update is available to me, but the gem dragons are shown as available... I must have bred a couple of fire dragons for hours last night trying to get a ruby, obviously without success. How do I get the crafting shop etc?
