I'm gonna evolve my Eevee into an Umbreon, and I find the easiest way to get friendship is by feeding it berries that decrease stats. But I'm not sure which stat is fine to decrease. I could walk around in SS, but that's tedious. What's the best stat to lower?
Special Attack
Umbreon is a staller and doesnt need Sp. Attack.
Either attack or special attack depending on which one you want to use
Speed and Sp. attack, a adamant/brave nature would be good with payback.
