How does the Tyrants of Lothal ally threat rule work, and does it apply in other campaigns?

Question

Accepted Answer

When the heroes take a Rebel ally in the Tyrants of Lothal mini-campaign, the Imperial player gains half the ally's cost in threat (rounded up) immediately and an optional deployment, then places strain tokens equal to half the cost (rounded down) beside his play area. Each Status Phase he discards one to gain 2 threat, and if the ally is defeated the remaining tokens are discarded for no threat. By the rules it applies only to that mini-campaign; using it elsewhere is a house rule.
