"The caretaker, Intor Arglenzt, finally put his lamp down and grabbed out his wand, "Animo Exsterno!" A dozen statues appeared at the entrance and back of the school which moved when Mirumorz's Army/Evil Group/Bad guys looked away"
—The spell

Animo Exsterno is a spell which conjures suits of armour which help fight you in battles. They only move or attack the enemy while they are looking in the opposite direction.

Intor Arglenzt used this in the Battle of Milkenshland.
