Castle upgrade costs

Not 100% but I thought it was a little above 10,000 elixir when you reach 20. There's a chart floating around here somewhere.

Ok thanks, I upgraded a few more times so i've added some of the later ones in the opening post.

I'm at 18 and the next upgrade (19) is 8500. Hope that helps!
