Sealing magic

The air popped under the crushing weight of Korgath's force. Set flinched as the sound pierced his ear.

He waited for the force to hit and the ground to break and splinter, but it never came.

Warren stood before the twisted beast. Not even a single strand of his greying hair out of place. His armour was black and stone-like, and a broad greatsword rested on his shoulder.

A golden magic formation spread from Warren's feet, beautiful patterns that formed a circle around Warren and Korgath. 

The damage from the Cruncher's heavy blows could not spread beyond this circle. 

Korgath's unnaturally long arms slammed against Warren's greatsword, and the air around them compressed like mist and exploded. Warren met each of the terrible blows with indifferent blocks. 

Set had to force himself to focus on his fight, dodging as a Crusher almost took off his head.
