I was looking on the database and noticed the move recover on a moveset for Palossand. I then thought "is there a difference between Recover and Shore Up (its signature move)?" After some research, I found out that Shore Up heals more HP in a sandstorm.
However, I then remembered the move Slack Off, and looked at its Pokedex entry on the database. It appeared to be identical to the move recover, from effect to PP, to even its Z-Move effect.
So, are there any differences between Slack Off and Recover?
