I don't think that would be a good idea because if it was in beatable people would complain about it and wouldn't want to.play the game because they just get wrecked every time plus if it was that dragon vs it self I the battle would go on forever , good idea though
Say your at level one you should get 2 gems and when you go up to level 10 you start getting 5 then when you get to level 20 you start getting 10 and so on
Because you.need more gems to level up
Tell me if you think this is a good idea...
Also you should get.gold and food when leveling up
