Your Ward of Dawn blinds enemies that enter it. Guarding with Sentinel Shield temporarily blinds nearby enemies.
Weapons of Light persists after exiting Ward of Dawn. While Weapons of Light is active, final blows or sustained damage grant stacks of The Saint; Void and Kinetic damage sources also trigger a suppressing burst.
Picking up Ward of Dawn consumes all stacks of The Saint and extends its duration based on how many stacks were consumed.
