I feel like Crypsis is kind of poorly written because it doesn't explain when you're expected to spend the maneuver to reset it. I can read it three ways:
After you use Crypsis, it gets damaged unless you spend a maneuver...
1) ...immediately, this round.
2) ...at your first opportunity, before you do anything else.
3) ...before you use it again, like a digital version of Limited Ammo.
