Boss 3 The first thing to be aware of in this fight, is that Cooke is being held by Tentacle C in this fight. Now each of the Tentacles have the ability Soul Drain which will take between 20 and 30 HP. They also have the ability Energy Drain which will take between 40 and 50 HP as well as some MP. If she dies, it's an automatic game over. Because of that, you should start by having every single one of your attacks being used on Tentacle C. Have Jansen casting Flare, while Seth and Kaim attack. Once Cooke is freed, she'll be added to your back row, making the fight a little easier.
