Battle Dungeons are combat-focused challenges where Ryoma leads a squad of Shinsengumi troops into dangerous areas to clear out enemies and retrieve valuable materials. These are excellent for grinding experience, money, and rare crafting components.

How to Access:
- Battle Dungeons become available after progressing a certain amount in the main story and joining the Shinsengumi.
- Access them from the Shinsengumi Barracks.
Gameplay Mechanics:
- Trooper Cards: You can equip up to four Trooper Cards, each representing a Shinsengumi soldier with unique skills and abilities. These cards provide passive buffs and active skills in combat.
- Squad Management: Level up your Trooper Cards, fuse them, and strategically choose which ones to bring into battle to complement your combat style.
- Dungeon Layout: Dungeons consist of multiple rooms filled with enemies. Clear each room to progress.
- Boss Fights: Each dungeon culminates in a boss fight, often against a powerful ronin or bandit leader.
- Rewards: Earn experience for Ryoma and your Trooper Cards, Ryo, and valuable crafting materials upon completion.
Battle Dungeons are the best source for high-tier crafting materials needed for powerful weapons and armor. Prioritize upgrading your favorite Trooper Cards and experimenting with different combinations to maximize your effectiveness.
