At the end of the Hexagon, you'll encounter Morag, a monstrous creature responsible for Coffinwell's plight. This is your first major boss battle, so be prepared. Morag primarily uses physical attacks and can occasionally cast spells. Focus your strongest attacks on her. If you have a Warrior, use their 'Foresight' ability to boost defense or 'Helm Splitter' to lower Morag's defense. Your Mage should use offensive spells like 'Frizz' or 'Crack', while your Priest focuses on healing with 'Heal' or 'Midheal'. Your Minstrel can provide support with 'Oomph' to boost an ally's attack or 'Accelerate' to increase agility.
Keep your party's HP above 50% at all times, especially your healer. If Morag targets a single character with a powerful attack, be ready to heal them immediately. Don't be afraid to use items like Strong Medicine or Magic Water if your MP runs low. After defeating Morag, the illness in Coffinwell will lift, and you'll receive a Fygg, a crucial item for restoring the Starry Express. Return to Stornway to report your success and continue your journey.
