A type of Verbal that causes the target to switch to all defensive actions for a short time. From the Accelerant core rules

"You are wracked with pain. You cannot attack or use most game skills. You may run, defend yourself by blocking with weapon skills and can use called defenses. Agony lasts for 10 seconds."

Despite the fact that it is called "agony" and mentions that you're "in pain" you do not take any damage from this Verbal. This should not be confused with Paralyze or Root.
