Midgardsormr is one of the first major bosses you'll encounter in the Grasslands. It's weak to Fire damage, so equip Fire Materia on your primary attackers. Its attacks include a powerful tail whip and a poison breath. Focus on pressuring it with Fire spells and physical attacks. When it's pressured, unleash your strongest abilities to build stagger. Be prepared to heal poison status effects with Antidotes or Esuna.
