Ok here is another one of those deals where I'd like to give you the scene and then maybe you can suggest the most proper phrasing.
After my bad guy, Tyranus, kills the king, archers are ordered to fire arrows at him. He puts up the magic barrier and the arrows deflecet harmlessly. While they are reloading, he drops the shield and uses his energy spheres, slinging them at the castle towers and ramparts where the archers are at, casuing the stone structures of the castle to crumble and fall to the ground. With the threat of the archer's removed, he walks up to the castle's portcullis(a giant metal lattice-work style gate structure) and attempts to open it. Realizing that he cannot move it by strength alone, he casts a spell that violently expels an outward projecting freezing mist or frost that is immensely cold. The cold soaks into the metal of the portcullis, causing it to crack and creak from the stress of compression, and renders the iron brittle. After the spell is completed, he simply taps the metal with the back of his hand, and the whole portcullis comes crashing down like broken glass.
Once again, sorry for the long post.
