There was no reason to hide the smile that played over D'Angelos face as he watched Jahar's feats of strength. He had a pretty good indication of what that magic was doing now. It made sense, his lens had shown him some transmutive properties, mixed with other magical energies that he did not have the skill to analyze. But he knew more now than he did moments ago and he realized that if he had attacked blindly that very strength could have proven his downfall. 

"Yes perhaps you have overestimated us." He agreed, laughing at Jahars words. "It seems you've fallen to the same delusion and myths that 
everyone else has. We are but men." He said with a mock-bow, his hands coming to rest on the hilts of his swords once again. As he spoke his body began to work over-time, eyes-dilated, body trembling slightly as a rush of adrenaline filled his body. "But, since you have humored me, I will oblige you."

There were no further words as his hand moved with a blinding speed, his left hand dropping to his belt and retrieving green vial that he flicked out with surprising speed and accuracy. The target wasn't Jahar, but the tiles that were on the raised roof to Jahar's left. The Acid vile, unless Jahar went out of his way to try and catch the item, would shatter on the roof. 

D'Angelo came forward a moment after he threw the vial, his footing sure footed as he withdrew his long sword with his right hand, his left once again dropping to his belt, though he made no move to grab anything this time. He reigned back the speed at which he ran, which took incredible control as all he wanted to do was open the flood-gates. 

After a brief moment many of the tiles that the acid struck would begin to break off an slide down in pieces a couple steps behind Jahar. It wasn't an overly dramatic thing, and the amount of tiles that broke free was barely more than a dozen. The only thing of note would be that they would land behind Jahar and continue sliding down to the ground the same moment D'Angelo came in range, his long sword stabbing out stabbing forward and try to skewer his opponent in the gut. 

It was the type of attack that wouldn't cause him to over-balance on the slanted roof and throw himself off the edge. It also used his range to his advantage, knowing that if Jahar back peddled to evade the attack he would risk stepping on a loose tile, which in itself wouldn't cause much harm. But any misstep and loss in footing would cause D'Angelo to press that advantage further.
