How to increased friendship Eevee

[Spiritmon]

Normally, I use the EV decreasing berries. They help too.

The EV traning or the EV items like HP UP or Attack Up?

No, in Kelvar town there is a berry shop to where you can buy berries that can decrease your EVs if you mess up your EV training. I never mess up my EV training and mostly buy those berries for friendship. Just give the Pokemon soothe bell and buy 30 of the berries and use them for the Pokemon you want to raise friendship with. (You don't need to gain EVs to execute this) When it says, "It won't have any effect" Its friendship is maxed. That's how I do it.
