Navigate the Underground Sorcery Lab, defeat tough enemies like Bomber Morte and Poison Toad, and prepare for the boss fight against Bathin in Bloodstained: The Scarlet Engagement.

Walkthrough
  1. 1
    From the Save Room by the train platform, descend the stairs. Defeat the Assassin and Buer, being mindful of how the Buer can interact with the next Assassin.
  2. 2
    Break the weak wall to the right of the Buer to find an HP Max Up (#5).
  3. 3
    Continue down, dealing with another Buer and Assassin. Cerulean Splash can hit both if positioned correctly and ranked up.
  4. 4
    Enter the Underground Sorcery Lab through the door on the left at the bottom of the room.
  5. 5
    Upon entering, you'll encounter a Bomber Morte, a tougher variant of the Morte. Defeat it before it overwhelms you.
  6. 6
    Above the Bomber Morte, you'll find a Sidhe, a stronger version of the Carabosse that casts magic.
  7. 7
    Further up is a Puppy. The low ceiling may make magic attacks preferable to jumping on its head.
  8. 8
    Beyond the Puppy are another Sidhe and Bomber Morte.
  9. 9
    Drop down the other side of the room and open the Blue Chest (#1).
  10. 10
    Go through the door on the bottom left.
  11. 11
    In the next room, you'll have a brief chat. Proceed through the door on the left into another multi-tiered room.
  12. 12
    Watch out for three Poison Toads near the entrance. These inflict a potent poison. Use ranged attacks or magic like Flying Edge to defeat them safely.
  13. 13
    Continue on the bottom level. Open the Blue Chest (#2), defeat the Bomber Morte, and check the Bookcase on the left.
  14. 14
    Enter the lower left door to find another Save Room.
  15. 15
    When ready, equip ranged weapons and magic. Head back out and ascend the ramp to face the boss.
