•Location: Midgardsormr is encountered in the swamps of the Grasslands at the end of Chapter 2.
•Party Composition: Ideally, you should include at least one character with ice attacks (like Aerith) and one with good stagger capabilities (like Tifa or Cloud).
Materia:
•Ice Materia - Midgardsormr is weak to ice, so make sure at least one character has this equipped.
•Healing Materia - Essential for keeping your party alive.
•Summon Materia (Shiva) - Shiva's ice-based attacks can be very effective.
•Level: Aim for around level 18-22 for a comfortable fight, but this can vary based on your strategy and upgrades.
Detailed Walkthrough:

Phase 1:
1.Initial Attacks: Midgardsormr starts with basic physical attacks like Headbutt, Snap, and Coil.
2.Strategy: Dodge or block these attacks. Use this time to build up ATB bars with regular attacks for casting spells or using abilities.
Phase 2 (around 75% HP):
1.New Attacks: Introduces Scorching Breath and Devour.
2.Scorching Breath: Run away or hide behind trees when charging up; it's a sweeping fire attack.
3.Devour: Can capture a party member; quickly switch to another character and attack the Cranial Dome to free them.
4.Strategy: Begin using ice spells like Blizzard on the Cranial Dome for extra damage and to pressure Midgardsormr.
Phase 3 (around 50% HP):
1.Cutscene and Beta: Midgardsormr will use Beta, which causes AoE fire damage but also signals a phase change.
2.Strategy: Use this opportunity to heal if necessary. After Beta, Midgardsormr's aggression increases, so be prepared for more frequent attacks.
Final Phase:
1.Aggressive Attacks: Midgardsormr uses more aggressive moves like Chomp and Toxic Waters.
2.Toxic Waters: Creates a poison cloud; use Antidotes or run to the edge of the battlefield to avoid it.
3.Strategy: Continue using ice attacks, summon Shiva if not done already, and utilize Synergy Abilities to stagger Midgardsormr for maximum damage.
Strategies:

•Exploit Ice Weakness: Use any ice-based abilities or spells whenever possible, focusing on the Cranial Dome when it appears to pressure Midgardsormr.
•Synergy Abilities: Use these to stagger the boss quickly. Abilities like Partners in Pain (Cloud and Barret) or Synchro Cyclone (Cloud and Tifa) are particularly effective.
•Summon Shiva: Her ice attacks can deal significant damage and help manage the battle's flow.
•Defensive Play: Keep your party's health up, using defensive skills or items when necessary.
Tips:

•Character Control: Control Aerith for magic damage or Tifa for stagger if you're focusing on melee. Barret can be useful for ranged attacks when Midgardsormr is out of melee range or in the tree.
•Avoid Fire: Since Midgardsormr resists fire, steer clear of using any fire-based Materia or summons like Ifrit.
•Stagger Management: Use abilities that build stagger quickly during pressure phases.
•Positioning: Use the environment; hide behind trees to avoid Scorching Breath and move to safer zones when Toxic Waters are used.
•Limit Breaks: Save these for when Midgardsormr is staggered or near defeat for maximum impact.
•Party Buffs: Use Aerith's Arcane Ward for doubled spell effects or Barret's Lifesaver to absorb damage.
