Dance

You dance for an ally within your sight, said ally has to be at most 20 ft away from you, any farther and you will fail, the dance inspires the ally it was used on to act again, this spell cannot be used on another ally that knows the dance spell and can only be performed every other turn the user takes. 

Grants +1 action to an ally that has already acted, will not stack and cannot be used on an ally that has yet to act.
