Root chalice that breaks multiple labyrinth seals.
When used in a ritual, this sinister chalice summons the Sinister Resonant Bell. The bell-ringing woman appears to be a mad Pthumerian. According to the Choir, the land of Isz lies in contact with the cosmos, which allowed the Great Ones to function on transcendental planes of thought.
Note: Additional rite Sinister Bell is for online use only. The bell-ringing woman does not appear offline.
