It is a lost magic type ability. The attack sends dragon slayer magic threw the user and he can emit it from one certain object. Similar to holder magic in a way.
For users with dragon slayer magic, it absorbs the energy and amplifies it with a Lacrema of the same magic type. There are seven diffrence stances that have been learnt for this magic.
This stance protects its user by forming a pair of wings on the user, that allow to defend himself against attacks, or to fly(similar to the wing of Exceed).
This stance is for offensive, it is similar to the fire dragon roar.
