Storm Mail

Storm Mail (暴風衣 Bōfūkoromo lit. Storm Robe) is a Wind Magic Spell.

Description
One of Erigor's trump card spells, he can create an armor of wind which not only increases his defenses, but also augments his destructive power. Although the winds created by Erigor's Storm Mail can blow out fire Magic, Natsu was able to strip off Erigor's Storm Mail by heating the surrounding air with his flames.
