He also has another move which shuffles the party and deals 10 stress damage, making this boss very annoying to deal with if you have a team that relies on party placement.

The Shambler will summon more if they die off, making killing them a bit unattractive, so try and focus the boss down instead. These tentacles aren't too strong when they first come into the fight, but each time they hit successfully they will be buffed quite a high amount. His main form of attacks are attacks that move him either forward or backward and deal either bleed or blight, while also summoning little Shambler Tentacles. If you run away from his fight, he'll show up in the next one. Your party will always be surprised when fighting this boss, no matter the circumstance. It will summon the Shambler and you will have to fight him in total darkness if you do so. The Shambler is an Eldritch boss that can appear in one of two ways: either as a fight in a hallway when your party is in total darkness or whenever you use a Torch on a Shambler's Altar curio, an altar with a red orb in the middle.
