Steve utilizes the Laceration status with those ultra-sharp scales of his. Now, I'm assuming that Savage Jho's swelling muscles and blazing aura of draconic energy equals a very high blood pressure, especially considering that he's constantly enraged. A few scales in the right places and Savage Jho would bleed out in a matter of seconds.

Backing up my main point, Steve can also use those scales for defense. Imagine Jho biting into a razor-sharp pine cone wyvern.
