Sky Dragon's Roar

Sky Dragon's Roar (天龍の咆哮 Tenryū no Hōkō): is a Sky Dragon Slayer Magic spell used by Wendy Marvell

Description
An air version of Dragon's Roar. When using this attack, she breathes a hurricane-like blast at her target. It is unknown what its strength is, but it was powerful enough to destroy one of Nirvana's Lacrima crystals, so it could be very powerful. So far this is the only offensive ability she has shown.
