I was doing medichamite quest. I completed the entire quest and just had to defeat the mega medicham. I had one level 49 ot. I equipped it with focus sash. In the battle the mega medicham hit my medicham and mine lived with one hp and used counter.

But, Counter didn't kill!!

I lost nearly 30k+ amount after losing.

Please respond for the following.

Unfortunately, there is nothing we can do as this was a miscalculation on the damage that was going to be dealt by the player. Counter did the intended damage mechanic here, but Medicham was barely able to survive the hit. Counter will deal 2 times the exact damage that was received by the move's user in the same turn, as long as this damage was dealt by a physical move.

 

Thus, leveling up your Medicham more will increase its Max HP, which will in turn increase the damage that will be countered with the move, as more HP will be depleted when Medicham hits you.

 

Thus, just level up a few more levels and retry the same strategy!
