Swing is an action (character animation) that occurs when your weapon deals damage (unless the target dodges).[citation needed]
On-swing attacks wait for your next swing to happen (
[Raptor Strike], 
[Heroic Strike], 
[Maul].) They are opposed to instant attacks.
The amount of time between two swings of a single weapon is equal to your attack speed.[citation needed] Parrying reduce the time until your next swing.[citation needed]
