Then Aragorn lead the way, and such was the strength of his will in that hour that all the DĂșnedain and their horses followed him.

Strength of Will

Strength of will is sorely underrated. 0 cost is nice but you do have to exhaust a character. However, if characters are ready then there probably not going to be in combat so you're not losing an action. Nice, cheap location control.
