Sobering Slap is the name of two distinct abilities in the Dragon Quest series. One slaps an ally out of confusion or wakes them up and the other prepares the user to counter a physical attack when attacked. In the 3DS version of Dragon Quest VII, Sobering Slap is renamed to Rude Awakening.
Mineuchi is a hybrid ability learned by advancing to rank 5 as a Warrior or Shepherd immediately after completing the other. In the 3DS version, hybrid abilities no longer exist and Rude Awakening is instead learned by advancing to rank 5 as a Warrior.
In the 3DS version, Sobering Slap is learned by advancing to rank 2 as a Jester. It prepares the user to launch a counter attack after being targeted by an enemy's physical attack. It is similar to Retaliate from the PS1 version.
This ability is learned with 32 skill points allocated into Litheness skill.
Sobering Slap can be learned by Sylvando through his Litheness panel for 8 points, but has already been learned by him when he joins the party. It can remove sleep, confusion, beguilement, or paralysis from one party member for 4 MP.
