Star Wars: The Fringe
Wounds and Strain
This represents the physical damage that your body takes during a combat. If your Wounds exceed your Wound Threshold, you are knocked out and suffer a Critical Injury. It also takes longer to heal Wounds than it does to recover strain.
A character’s strain represents the ability to not break under pressure and non-lethal resistance, typically, when being shot in combat, Strain is the first thing to go before going into Wounds. Soak will still apply to the character, however, once the Strain Threshold is expended, damage proceeds into Wounds.
Obligation can affect the character’s Strain, as it represents a character worrying over his obligations. How he needs to do something, or how he needs to provide something to somebody who really needs it.
An example of how strain works in the original Star Wars trilogy is Han Solo. He has a price on his head by Jabba the Hutt, and he is trying to pay it back, this may represent some mental strain when Han Solo is thinking about Jabba. However, at the end of The Empire Strikes Back, Han Solo encounters Boba Fett who takes Han Solo back to Jabba the Hutt for the price on his head, which would be Obligation catching up with him.
