In the Arena, Morren is a battlefield nuisance. His primary ability defends an area centered on his location, allowing him to protect his allies for a number of attacks equal to successes rolled. When an enemy attacks an ally, Morren Rushes to that enemy, Intercepting their attack, and dealing half a heart of damage in return.

Morren's item choices are between a Sword and Shield or Fist Weapons. The Sword and Shield allow Morren to taunt enemies into attacking him, while the Fist Weapons allow him to act more like an Assault Champion, and gamble for extra attacks.
