You’re transported to a recreation of Dark Lord Gaol’s room. Waiting for you there is the Dark Lord herself as well as Magnus. Both are here to fight you as part of your Three Trials. Gaol still has her impressive arsenal of magic. In this battle, she stays at a relatively safe distance, casting her spells at you. Magnus does everything in his power to get in your face and stay there, with high-speed charges and his impressive sword reach. Between the two, it can be a very tough encounter, as they coordinate their offense quite well.
Your approach to this fight depends greatly on what weapon you’ve brought to the field. Weapons like cannons, bows, and palms all have very solid ranged attacks, which can allow you to take down Gaol first. If you’re using swords, claws, or clubs, Magnus will probably be your first target. He’s so aggressive, he’ll always be putting himself in danger of getting smacked around by your melee attacks.
After taking down one of the bosses here, the loser drops a Drink of the Gods. Try to finish off the other half of this pair without taking more damage—you’ll need all the health you can muster for the next fight.
