Bout how many gems do u think I would need to complete the dungeon all the way

But which dungeon are you referring to?

I mean monster cave

@zelly2 treasure cave? well over 10k gems

@zelly2 An optimistic estimate is around 17k gems. Which is around 550€ if you buy them on sale. Keep in mind this is a light guess. I'm pretty sure the cost is higher than 17k gems.

Could get lucky and it wouldnt cost you a bean. Let's us know how much you spent. Good luck. You'll need It!!!!!
