I finally got black dragon today! I reached 12m XP and then was crushed in a 1v1 duel, (which I think are stupid).
I had never even reached the monster tier!
wuts next tier
Black Dragon is the last tier.
it says 40M xp next animal
It's not really "next animal" though. It just unlocks "high fly".
oh
