Supply Boost

The Supply Boost is a feature of some buildings and items to increase all supply collections from the city by certain percent. Supply boosts can also be activated from the Friends Tavern by paying for it with Tavern Silver.

The Supply Boost is applied at collection time. The Supply Boost doesn't affect any supply collections from Great Buildings.
