The Red Soul is a powerful magical foe, and can be a challenge. In the first four rounds of the fight it will blast Fire VIII, Blizzard VIII, Thunder VIII, and Scourge VIII. It absorbs every type of offensive magic except non-elemental ones, such as Drain or Osmose. It also has a high resistance to physical attacks. However, it does not have nearly enough MP to support its high-powered spells, so after the first four rounds of the fight it will revert to using a physical attack that only does minor damage.
Everyone in the party should be equipped with at least Mythril-tier weapons, or they may have difficulty piercing the Red Soul's high Defense. A Cure spell of a decent level will provide enough healing for the party to withstand its initial onslaught. With the Ancient Sword found in the Snow Cave, there is a chance to place a Curse on the fiend, drastically reducing its attack power and durability.
