Expanded Attunement

Core Rulebook pg. 62
You can use beneficial mind-affecting envoy improvisations to aid allies who usually would not be able to gain benefits from mind-affecting effects, such as constructs, robots, and undead. If the improvisation grants a morale bonus, even allies who can’t normally benefit from morale bonuses gain that bonus.
