Dr. Mog's Advice
The Soulcage uses the group ranged physical attack Leaf Swirl, as well as the group magic fire attack Fira, so it pays to shore up your defenses with Protectga and Shellga, kupo! Other abilities at its disposal are Mustard Bomb, a physical attack that can Sap one of your heroes, and Ultimate Blast Wave, a ranged physical attack with a chance to interrupt the actions of your entire party! It can also use the group ranged physical attack Ultimate Leaf Swirl that ignores buffs to Defense, so even though it resists break debuffs, Exhausting Polka can help keep the damage down, kupo. When the Soulcage is on fire it uses the group ranged physical fire attack Fire Blades, and when it first goes up in flames it always unleashes Ultimate Fire Blades, a ranged physical fire attack that lowers your entire party's fire resistance! While burning, it is resistant to fire, and any fire attacks used against it boost its power, so use ice or water abilities to extinguish the flames as soon as you can, kupo! While its power is boosted it absorbs fire, and starts using the group magic fire attack Ultimate Firaga that ignores Resistance and can break the damage cap, so things could go south quickly unless you lower its Magic with abilities like Heathen Frolic Sarabande! It can also ignite itself with Fira, and it counters physical attacks once it gets low on HP, so you need to stay alert, kupo. The Soulcage is slightly weak to fire and holy damage, but fire abilities only make it stronger, so holy attacks are the best option! Because this foe is undead, healing magic will also damage it! Just be aware that it's immune to dark damage, and it resists all other elements, kupo!
