Bab 451: 4th Stage Battle 

As soon as he appeared behind the Hawk, Vicente used the metals around him to launch several ground attacks at the creature while using his second ability to force the beast's body downward.

By affecting the creature's electromagnetic field, he acted like a repelling magnet, causing the Hawk's body to move downward toward where giant spears were flying toward it.

Simultaneously with these attacks, darkness appeared around the Hawk's head, and Torne controlled the darkness to enter the beast's body and corrode its mental structures.

Tempest Hawks were known for their mental attributes, so this beast's pentagram may itself have a mental ability. However, having a mental ability and being completely immune to such attacks were two different things!

Torne was a ghost whose powers were very much focused on the mental part. As soon as he started to act against that Sovereign, he took some of the Hawk's attention away.
