Met this level 30 Indoraptor at 4.2k arena, really? And I lose the match of course.
Eventually you can have a lvl 30 indoraptor as well. I’m not sure what exactly you think is the hack or the bug?
His profile doesn’t show a level 30 Indoraptor
That is odd, I’d say glitch but his HP looks about right for a level 30.
