Darkness Dragon's Roar

Darkness Dragon's Roar (闇竜の黒怒気 Yamiryū no Kurodoki) is a Darkness Dragon Slayer Magic spell.

Usage
The Darkness Dragon Slayer's signature Roar, incorporating the element of darkness. The user gathers darkness in his/her mouth and releases it in a concentrated, destructive blast, capable of destroying everything in a wide area in front of him/her. The special ability of this particular roar is that or rotting anything on its way.

Mezar's particular roar has the tendency of behaving like a gaseous substance, being able of spreading through airspace in a slow rate but with equal effects on the surroundings.
