Chorus of Heroes
Major
While rare even by the standards of magical songs, this sacred song is capable of breaking through barriers that would leave foes serving great evil, or even being said Great Evil, invulnerable to even Silver Arrows.
This song can be performed in combat. If the caster begins to perform the song while in the presence of great evil, they are protected by a transparent shell that acts as a barrier. Nothing the forces of evil can do will affect the caster, although other foes and natural occurences can still affect them. If the caster is affected by an attack or otherwise forced to move or knocked prone while they are performing, the song fails, and no Magic is expended.
At the end of the caster's fourth turn after the turn where they started to perform the song, the song has been successfully played and the caster's and their allies' bodies begin to glow in a faint, golden light for the duration of the scene or encounter, only bright enough to illuminate themselves and nothing else around them. While glowing in such a way, all barriers that would leave foes invulnerable can be broken and dispersed by landing a single attack. This may also automatically reveal Weakpoints, depending on the foe.
