Zelas Phalanx (Japanese: ゼラス・ファランクス Romaji: zerasu farankusu) is an offensive black magic spell[1] which draws power from Greater Beast Zelas Metallium. It is an amplified version of the Zelas Brid that can affect several targets at once.
Interestingly, the only known user of this spell is Milgazia[2], the leader of the golden dragons of the Kataart Mountains, and because of this the spell was believed to belong to holy magic despite its name. Its true nature as a black magic spell was finally stated in the Slayers Reading guidebook.
