Sage Art: Flames of Hephaestus

This is Renya's most powerful form (other than a full fox transformation) while in Sage Mode. What happens is that Renya slowly begins to catch on fire, until her entire body is wrapped in flames. By adding senjutsu (natural energy) to this equation, the flames are not easily put out, and give further increases to the users speed, strength and stamina. The flames can also be used to heal others, hence the Apollo name. However, like the Sage Mode, the Flames of Apollo will put a strain on the users life and chakra reserves, so if used for too long, the technique can prove deadly.
