During the fight, morroval adds will drop down one at a time from the ceiling. Each one will run to a side room to gather several bat allies, then return to the main room to join the battle. The merrevail can be rooted or stunned to prevent or delay this from happening.
Mormoz can also be pulled outside of the entrance of her chamber, resulting in fewer adds during the battle.
