Upon using the ability, the target's last used skill cannot be used for the next 5 turns. If the target attempts to use a disabled skill, nothing happens and their turn is skipped. Disable can only block one skill at a time, and will fail if the it is the first move used in a battle or the target is already has a move disabled. It used to be called Disable Skill.
"Disable the target's last used move for 5 rounds."
