Some abilities have a “Spend X [Heroic Resource]” entry in the body of the ability. These grant additional effects to an ability, where X is the amount of your Heroic Resource you must spend to activate those effects. If an entry reads “Spend X+ [Heroic Resource],” you can spend as much of your available Heroic Resource as you like in multiples of X to increase the effect’s impact, as described in the entry’s details.
