You know, the more I think about it, maybe mount xp isn't as exponential as I thought it would be.
Maybe it becomes linear once you hit 10 stars (hint hint to tynon devs).

A more feasible and appropriate xp table would look like this:


Bear xp


1 star | 1000xp
2 star | 2000xp
3 star | 4000xp
4 star | 8000xp
5 star | 16000xp
6 star | 32000xp
7 star | 64000xp
8 star | 128000xp
9 star | 256000xp
1 moon | 512000xp
2 moon | 1,024,000xp
3 moon | 1,536,000xp
4 moon | 2,048,000xp
5 moon | 2,560,000xp
6 moon | 3,072,000xp (230,400 gems using taming)


This table looks more realistic than the one that just doubles xp every level.


Dragon xp


1 star | 2500xp
2 star | 5000xp
3 star | 10000xp
4 star | 20000xp
5 star | 40000xp
6 star | 80000xp
7 star | 160000xp
8 star | 256000xp
9 star | 512000xp
1 moon | 1,024,000xp
2 moon | 1,536,000xp
3 moon | 2,048,000xp
4 moon | 2,560,000xp
5 moon | 3,072,000xp
6 moon | 3,584,000xp (268,800 gems using taming)
