Approximately how long of a time without having to fight is considered "Out of Combat" for purposes of Stress renewal?
Take for instance the "tactical reserve wizard" Who goes into battle, blasting away, and when nearly tapped out of energy, opens a portal to the NeverNever, where he can catch his breath, and come back when he's got his second wind. How many exchanges will happen back at the fight while he takes a breather?
And what about the old standard, "I Veil and run away," with the pursuer failing to figure out which way you buggered off to. How long before the Stress Reset?
