Star Hero: Noble Ideals
Personal force field technology is extremely common. A sentient wearing a shield can still be knocked out, but they are unlikely to suffer serious injury while their shield is up. Shields have a few limitations: a) they take a second or two to activate; b) they are hard for the user to see/hear through (some brands have different issues); c) civilian models have 10-15 minutes of power per day.
Shield technology had a strong impact on Galactic culture and the law. In general it is not illegal, or at worst a minor crime, for shielded individuals to engage in “duels”. On the other hand, threatening or assaulting someone unshielded is a serious crime.
(In game terms, shields make it likely that users will take STUN but not BODY damage from most attacks. Raising a shield is a 0 Phase action, but cannot be Aborted to; this means that if someone catches you with your shield down, you could be in a world of hurt.)
