What uses do you have for using strain in your games. I use the 2 for another maneuver and there are a few talents that burn strain. The environmental as well. Is there any other ways you use strain?

Casting a spell costs 2 strain. The GM can spend to cause strain. Failing social skill checks can cause strain. Being targeted by a social skill check can cause strain.

Threat on magic roll can be used as either 2 strain or 1 wound (decided by the player)
