"Finally decided to drop the act, huh?" Kaden's voice dripped with contempt.

The old man chuckled darkly. "You're quite perceptive. But it's no use. You are no match for me, boy!"

The old man's form began to waver, and in seconds, he transformed into a different figure altogether—a humanoid creature with reptilian features, decked in dark armor and wielding a sinister-looking dagger. 

"I am Vrykloth, a shapeshifter, though you do not deserve to know my name before you die."

Heh. Kaden grinned. "Who said I need your name? I just need your mask!"

The other party heard this remark and couldn't help but become startled.

Kaden also knew that he was probably no match for him which was why before the creepy lizard guy could do anything, Kaden unleashed a [Fire Ball].

All this time while he was fighting the various elites, he had never used his real overpowered skill even once and he was specifically saving it for the guy.
