Nightmares were ferocious beasts. The level nine nightmare went all out using a soul attack skill. The black horn on top of its head glowed and a halo was manifested. The grey aura was but a disguise.
The fire type element spirit was born in the Imperial City of the Abyss and did not have any complex combat experience. None of its inherent memories from ancient times contained anything regarding nightmares.
The volcano that the spirit was born and lived in was considered an outskirt of the city. The spirit that could be allowed to exist there was level 13 at the highest.
It had been in the outermost part of the city due to chasing Nailisi. If it had not been clad in the fire armor, it would be killed by the rules of the plane a long time ago.
The fire type element spirit retained combat capacity at level 13 and it was all due to its armor.
