With the Written in Stone trait, when you use signets, such as signet of air with a 30 sec cooldown, it will only work for 20 seconds so you’ll be left with 10 seconds of the passive effect not working.
Likewise, sometimes the passive doesn’t activate at all when you load into a map until you use the signet or something that disables them (Mist Form, Ride the Lightning).
