13.5.2 Stun Mechanics

Some attacks will leave you in a state of being stunned. While stunned, you will be unable to perform a vast majority of actions until the stun wears off.

Once you have been stunned, there is a period of time afterward where subsequent stuns will have their duration reduced. It will remove 15% of the stun duration each time you become stunned again, and increases all the way up to a maximum of 60%. After 3 seconds of not being stunned, the stun reduction will fade and you can be stunned for the full duration again.

Some afflictions and/or defences can increase or decrease the amount of time you're stunned, so keep this in mind as well.
