This spell can only be used if the caster has half health or less. A 35 foot radius is formed around the caster. All light in this sphere is absorbed into the caster, leaving the sphere void of light. If the caster is a Radiant Genasi they gain a health point for every 3,000 feet squared of light absorbed(18,000 feet maximum). Seven levels after learning this spell you can cast it on another character within sight.
