Megido Arc

Megido Arc (メギドアーク, megido aaku) is a spell used by Memphis in novel 13 to defeat the middle-ranking mazoku Sardian. It is not known which category the incantation belongs to; its name is very similar to Megido Flare, but white magic spells are usually not offensive in nature. Slayers Reading, the only guidebook to list this incantation, only categorizes it as "elven magic".

The target of the spell is enveloped in an explosion of crimson flames. Notably, the flames deal damage on the astral side as well, as they were able to harm spiritual beings.
