Luthor Huss

So strong is the faith and charisma of Luthor that. when he joins a unit. even characters in the unit and models who are normally immune to Psychology will share Luthor's burning hatred for all blasphemies against Sigmar (Chaos Warriors, Beastmen, Daemons. Chaos Dwarfs. Khemrian Undead. Vampire Counts and Skaven).
Still, Luthor would never join units of warriors who are not devout to Sigmar. so he cannot join units of Knights of the White Wolf

iuthor can cast the Prayers as normal, but with a Power Level of 4!

Warrior Priests are blessed by Sigmar and can invoke the god's protection against the sorcerous powers of the enemy. As long as a Warrior Priest is on the battlefield, he adds one dice to the Empire player's Dispel dice pool during the enemy's Magic phase.

Sigmar's protection of Luthor manifests itself in a supernatural halo that surrounds the prophet in battle and protects him from evil. Luthor has a 4+ Ward save and causes fear in the enemy.
