I'm trying to make my umbreon do heaps of damage with dark pulse and nasty plot is a good way to do this but I can't find it. If not where is calm mind
Nasty Plot is not a TM. Nor can Umbreon learn Nasty Plot at all.
And Umbreon can't learn Calm Mind either.
Nasty Plot would have to be bred onto a Pokemon through egg moves. Calm Mind can be bought at the Battle Frontier for 48 BP.
There is no Tm for nasty plot (unfortunately). Tm 04 (calm mind) can be purchased at the battle frontier for 48 battle points.the battle frontier is located to the direct left of olivine city with the entrance on the beach.
