Flames of the Cold-Hearted

The Flames of the Cold-Hearted (Reiketsukan no Honō れいけつかんのほのお) is a forbidden type of Fire Magic-based Ring Magic which momentarily converts all of the caster's sympathy, which is referred to as the Warmth of the Heart (Kokoro no Nukumi こころのぬくみ) in this context, into a flame which the caster will be fully capable of manipulating to the utmost extent.

Its utilization absolutely requires that one be in possesion of an Orichalcum Signet-Ring (Oriharukon Mitomeintsukiyubiwa みとめいんつきゆびわオリハルコン).
