Region Overview

Pharloom Bay - Coastal region in Silksong Sea of Sorrow DLC

Pharloom Bay is a coastal region at the southeastern edge of Pharloom, where saltwater meets ancient stone. This is where the "salt-stricken waters" mentioned by Alchemist Zylotol lie - the very waters where Plasmium was first discovered.

The area was originally shown in Silksong's 2019 reveal trailer featuring gorgeous blue waters, barnacle-covered structures, and a quaint village populated by shell-wearing NPCs. Cut during development (around 2021-2022), it finally returns in the Sea of Sorrow expansion.

Quick Facts

  • Location: Southeast of Bilewater, above Verdania
  • Map Color: Bright blue (indicating water)
  • Environment: Saltwater shores, hot springs, coral caves
  • Difficulty: Late-game recommended
  • Total Rosaries: 8 (including 2 hidden)

How to Reach Pharloom Bay

Getting to Pharloom Bay requires you to have progressed past the Bilewater area in the main game. Here's how to find the entrance:

Step-by-Step Route

  1. Travel to the southeastern section of Bilewater
  2. Look for a flooded passage near the border with Verdania
  3. You'll need the Diving Bell Tool (obtained earlier in the DLC) to proceed
  4. Take the submersible through the underwater tunnel
  5. Emerge in the Salt Grotto, the first sub-area of Pharloom Bay

Pro Tip: Make sure to stock up on healing items before entering. The first few rooms can be challenging if you're not prepared for aquatic enemies.

The Plasmium Origin

Lore tablets reveal that Plasmium was first discovered in the deep waters of Pharloom Bay by Zylotol's master. The substance rises from thermal vents in the ocean floor, possibly connected to something ancient sleeping in the depths...

Secret Areas

  • Hidden Shrine: Behind a breakable wall in the Tidal Caves. Contains a unique Charm.
  • Sunken Ship: Accessible via a secret passage in The Anchorage. Contains Shell Fragments.
  • The Abyss Gate: Mysterious locked door that may connect to future content...

Exploration Tips

Pro Tips

  • Equip the Tidal Crest early - it significantly improves underwater mobility
  • Watch for bubble streams - they indicate air pockets in underwater sections
  • Return to the Thermal Springs after boss fights for free healing
  • Talk to the Shellkeeper multiple times - dialogue changes as you progress
  • Use the Plasmium Phial in the Depths - it has enhanced effects here

Heads Up: The Tidewarden boss has a second phase that only triggers if you've collected all 5 Lore Tablets. This unlocks additional lore and a secret achievement.
