Brightsong

Brightsong was a wizard spell from the schools of abjuration, alteration, and enchantment.

Effects
Brightsong was unleashed when the incantation was sung. This spell created a sphere of free action centered around the caster. The sphere would follow the caster if they moved about but did not work under water. In addition to the benefits of free action, all locks, including magical ones, were opened and all knots were untied within the sphere.

There was a chance that any creature under a form of magical compulsion, such as a geas, would be freed from the compulsion when entering the brightsong sphere.

Components
This spell only required a Verbal component to cast.
