Gunfire crackled through the air as Ringo looked down on his friends. He could see Jack, hear his call for help. “Well, why not?” He shrugged, then flipped from the roof falling silently toward the ground below. He aimed for the very center of the dark orb using his momentum to boost a punch with his cybernetic arm. He gripped his knife tightly in the other hand, ready to plunge it into his opponent’s flesh.
Blinded he should have no reason to detect an attack from above. I am aware that Iron Fist can amplify his senses to very high levels, but between the ambient noise from the gunfight and Jack's yelling he should not hear my relatively noiseless attack from above. I think I've already posted all the feats that would apply to this post in previous posts. Let me know if you need anything from me.
