No matter how magical it looked to Blake's eyes, seeing someone casting a spell without a single rune, Blake didn't spare the time to show his awe and instead bolstered his defense to prepare himself for the humanoid demon's attack.
From the humanoid demon's hand, the gathered darkness element finally made a solid construct as a darkness spike, a very similar one to the darkness spike that Blake had cast very frequently before he got the fiery nether bloodline power from Cyra as his main method of attack right now, appeared from the humanoid demon's hand.
And it seemed to have the same characteristic as the ordinary darkness spike spell that Blake knew since it didn't waste a single second to sprout from the humanoid demon's hand and went straight into Blake's darkness barrier spell.
