Gauntlet Smash

Despite the tremendous backlash he endured from the previous attack which resulted in a broken left arm, Vepar managed to keep his enlarged gauntlet steady enough on his right hand for the punch to hit the unstable floating fortress. 

By dropping the fortress to the ground, Jin hoped that it would disable most of the features in it. Weslie mentioned that the steam technology systems she recalled creating were not as sturdy as she had liked them to be. This was mainly because she had been forced on a very strict timeline for some reason. At that time, she was only given enough resources to make the floating mechanism.
