[It's a difficult skill, though one Duster thought was easy to explain. Battles have a sort of musical rhythm to them, and by listening close enough, anyone can have an idea of when to hit. The trouble was with timing them correctly.]

Sometimes. Not everyone can change the flow of their fighting on the spot, it'll knock them off balance. There are enemies that have styles that use unusual rhythms, but most I've met are steady. It's only a matter of feeling their heart.

[Does that make sense? There are fights with steady beats, and those with off-kilter beats and sudden pauses, and even Duster has trouble with the latter.]
