I'm going to elaborate from what iamtfc said as of now only the downward smashes work whether this will be changed who knows.
The fastest way is using level 2 but instead of reloading a group of enemies over and over get the enemy count down to one and make this rat dizzy.
Save the game once you are stood next to the dizzy rat the nearer you are the easier it is. Then keep reloading that save 100 times if you miss the attack use the rewind feature it's a grind but it's the most effective way
