Ere we go!

This spell is inspired by The Warhammer Fantasy Universe.

As the caster chants and dances, a stream of savage energy leaks forth and afflicts all friendly targets within a 40 feet radius, boosting their fierceness and prowess! While concentrating, all friendly creatures within range gains a bonus to their damage equal to the casters casting ability modifier and their AC by +1.

While concentrating, the caster is unable to cast any other spells or preform other actions, save from using his or her movement.
