recently, i've been playing Pokemon x and was leveling up my Tyrunt so it would evolve into Tyrantrum when it didn't evolve at lvl.39. It is now at lvl.42 and it never held an everstone. Please help me and tell me why it won't evolve.
Are you leveling it up during the daytime; if not then thats your problem. For Tyrant to evolve it has to be at or pass level 39 during the daytime and level up once more. If you are leveling it up during th daytime then something is wrong and you may want to try to get a new Tyrant or restart your game.
