Dragon prince

[gameplayer123]

You unlock it at town hall 10 it cost 60000 dark elixir to get at the start

Dragons are OP. you train 20 dragons, then the Dragon Prince summons another 10. 3 star easily.

You need to add WAY more details!

1. Regeneration time
2. Level up cost
3. Level up build time
4. Ability unlock information

Furthermore, and most importantly, there is no reason to further separate the strength of a TH 9 and a TH 10, so the idea of a dragon prince is more or less unneeded and OP.

I think this is a hero.

Sorry, heroes are ruled out.
