I haven't seen an 8th-tier lava demon in many years, Urien thought, putting away his wand. It is them who inspired Krassu to become a melee magic caster.
They were strong in body and had matchless talent for fire magic. Basically, each and every one of them was a fire magic caster. Hundreds of years ago, they had been one of the 10 most powerful demon subspecies.
Later, however, the lava demons somehow couldn't even reach the 6th-tier, as if they had been cursed or something.
When the war spread to their lands, without enough strong young ones to defend them, the once dominant lava demons had almost been wiped out. The ones that had survived were now living in the depths of the Demon Islands; rarely did they come out.
This demon is most likely the strongest of all lava demons, Urien thought, surprised.
A 10th-tier lava demon was basically a killing machine, and was capable of turning the tides of a war.
