Optional encounter, when the player tries to access Charlotte's Cell, without having pacified Valna and Vigna with their dolls.

Strategy

Just run away as there is nothing you can do to defeat them. All your attacks will just miss; you need to find their dolls to get the Green Key.

While they can technically be poisoned, and will lose health, there is no practical benefit for doing so, and relies heavily on both finding a weapon drop with the Poison attribute, and being lucky with the RNG.

Due to their relatively passive nature and invulnerability, they can be used to grind magic and weapon levels.
