Firecaller

Firecaller is an enemy added in Revelations Chapter 2. Its Glacier counterpart was later added in the Neapolitan Update.

Glacier Firecaller
The Glacier Firecaller wanders around aimlessly. When it detects the player is near a heat source, such as a fire place it will launch a tear from said source towards the player. Heat source can be Fire places, Grill O' Wisps and lit ground Fires. After receiving enough damage, the Firecaller will collapse into a stationary second phase. In this phase, Firecaller will shoot a single tear at the player when they are close.

Firecallers also emit a heat source in chill rooms.

Tomb Firecaller
During Firecaller's first phase, he will walk around the room randomly and occasionally attack, causing homing tears to shoot from the brazier fires located in corners of the room. If there are any fire places in the room, those fires will glow purple for a second and also send out a homing tear towards the player. After receiving enough damage, the Firecaller will collapse into a stationary second phase, causing all fire places in the room to extinguish and shoot out multiple small fire projectiles. In this phase, Firecaller will shoot a single homing tear at the player when they are close.
