Eilistraee's moonfire

Eilistraee's Moonfire was a spell granted by the goddess Eilistraee to her priestesses and, at her will, worshipers. It was a beacon of light, whose intensity and color could be controlled by the creator at will (ranging from a faint glow to a clear, bright -but not blinding- light). Moonfire had the same intensity as moonlight, and it was generally used as a light source for reading, to see in the dark, as a signal for communication or for artistic purposes. Manifestations of moonfire lasted as long as its summoner desired and concentration was not required to maintain it. This spell and the darkness spell negated each other. Manifested moonfire could move as the creator wished and it was always attached to the her body (even if experienced Priestesses could sustain the moonfire even when it didn't touch their body, like the spell dancing lights). The radiance could move around the creator's body as fast as desired, however it moved up to 6.6 feet per second when far from the caster. The manifester could guide it in any direction, through any opening, and cause the glow to appear in any size. Eilistraee could also occasionally choose to gift any creature the power to temporarily manifest her moonfire.
