The Way of the Wicked
A cohort can be assigned to aid your minions. Any cohort so tasked is unavailable for anything else that week. They are busy with underlings. A cohort adds their revelant ability score modifier to an Action Check. For example, Grumblejack the ogre could add his +6 Strength modifier to any violent actions. If an action aided by a cohort loses Survivability, the cohort must make a Fortitude save vs a DC equal to the task difficulty or die.
