Flame of Rebuke

Flame of Rebuke is a Caster Type Magic utilized by Jellal Fernandes. The spell, when released, creates special, golden flames on his palm. Jellal gives to Natsu in order to defeat Zero. When it was eaten by Natsu, Dragon Force was activated. Natsu describes the feeling of eating the flame "like eating Etherion". In Fairy Tail: Shooting Star, Chall Factice utilizes this magic in various ways thanks to her Lost Magic "Conversion", applying it similarly to regular Fire Magic, Fire Dragon Slayer, and Flame God Slayer. As it turns out, the Flame of Rebuke is a byproduct of Gailardia H. Vigilia's Blaze Cross Slayer.
