The Hermit Shadow is a unique boss that tests your ability to adapt to a non-standard encounter. It has no elemental weaknesses but is susceptible to critical hits. Your party should be around Level 18-20.

Boss Details:
- Hermit Shadow: No elemental weaknesses. Resists all elements. Uses powerful Electric magic.
Strategy:
- Critical Hits: Focus on physical attacks with high critical rates. Skills like 'Rebellion' or 'Revolution' (from Personas or Skill Cards) can boost your party's critical chance.
- Physical Skills: Use physical skills from Junpei, Akihiko, and the Protagonist.
- Electric Resistance: Equip accessories that grant Electric resistance if possible.
- Healing: Yukari's healing is crucial to mitigate the Hermit's electric damage.
- Theurgy: Save your Theurgy attacks for when they are fully charged to deal significant damage.
This fight is a war of attrition. Focus on consistent physical damage and critical hits. Keep your party's HP high and use items as needed. Fuuka's analysis will confirm its lack of elemental weaknesses.
