How does it go higher then that?
Jynx, Gengar and Mismagius can pull it off to an extent as they have sleep inducing moves - Absol doesn't.
Anyway, I'm getting way off topic now unless this has become an Absol discussion thread while I wasn't looking.
Even if you're correct (I'm certain they have 2, and each 1 is 12.5%), they have 3, which means they don't add the one that you say every offensive move has. Add one from Super Luck and you get 1 + 3 = 4.Nightslash(and the other high crit moves) have 3 crit levels
