Fist
The warforged closes in to the Giant Hunter with a single graceful jump. He then opens his big hand fully into a single blade. He then proceeds to make four stabs at the Giant. "Raging Lion Spear Fang!" The air seems to bend around the giant metal glove of Fist and fire engulfs the fingers as he pierces through the Giant.
