Walkthrough for Bloodstained: The Scarlet Engagement's Double Dealings quest. Find all Blue Chests, Red Chests, items, and defeat the Doppelganger boss.
Walkthrough
- 1Equip the Deep Sinker shard. Enter the _Forbidden Underground Waterway_ from Arvantville under the castle drawbridge.
- 2In the waterway, hop into the water and run to the lower-right corner to find Blue Chest #43.
- 3Continue to the western _Teleportation Room_ in this region.
- 4From the teleportation room, go left. Pass through the long room and skip across the room filled almost entirely with water.
- 5In the next tall room, drop into the water at the bottom to find Blue Chest #44.
- 6Return to the room that's almost entirely filled with water. Watch out for Deeseama and Glashtyn.
- 7Go through the door on the bottom right to find another Glashtyn and a Red Chest #46 containing 2,000g. Grab the HP Max Up (#46).
- 8Return to the previous room and make your way across the bottom to Blue Chest #45 before exiting left.
- 9Enter a long room with a Glashtyn. Attack it from above, then move left. Use Reflector Ray to bounce through a small space in the wall to the left. Beware of the Glashtyn on the other side. Defeat it and go through the door on the left.
- 10In the new room, you'll encounter a Scylla. Wait for it to open its mouth to attack, then hit it. If you attack from above while it's recoiling, you can deal more damage.
- 11Destroy the Scylla and open the Blue Chest #47 next to it. Proceed left.
- 12Defeat the next two Scylla enemies (one on the ground, one on the ramp above). Climb out of the water, watching for a Seeker on the platform to the left.
- 13Climb the platforms on the right to reach Green Chest #48 containing a Swordfish.
- 14Destroy the wall across from the Green Chest for Plunderer’s Ring #48. If the platform collapses, use Reflector Ray from the bump on the right, aim for the right side of the gap, Double Jump at the top to loop around and land on top.
- 15Drop down, go left, use Reflector Ray to get through the gap in the wall, and climb up to the door on the upper-left.
- 16Enter the Secret Sorcery Lab. After the scene, go through the door on the left.
- 17In the next room, ride the huge guillotine blade upward by climbing on top of it. Avoid the spikes at the top.
- 18On the level above, defeat the Dark Elemental and Lamashtu.
- 19Climb up to the doorway on the right. Open Blue Chest #1 inside.
- 20Return to the previous room, cross to the left, and grab Blue Chest #2 just left of the guillotine blade.
- 21Drop down and check the Bookcase #3 to the right of the guillotine blade.
- 22Go through the door on the left into a tall room. Deal with the Dark Elemental below.
- 23Head to the bottom of the room and go through the door on the right to find a _Save Room_. Save your game.
- 24Return to the previous room and go through the door on your left to face the boss.
