What exactly does the fire gem do? I've killed the big dragon and got it, but there is no description so I don't know if I should hold on to it, sell it, or just keep in in my warehouse.
I've gotten myself stuck. I beat all the platinum cups and everything but now I only get the month of March and the Little Giant cup never comes up. And some monster battles get real glitchy too. I just fought a monster with 0 stats, 0 health and i did 1800 damage and nothing happened and then eventually I couldn't even attack. I would click the attack button and my energy bar would drop a little but not really anything and the attack graphic wouldn't happen. Everything just kind of broke.

It's useless right now, but it will have an important use in the future, which is why you can't sell it.
