Heated Chamber. The Brazen Bull is a macabre torture device that detains a victim within a chamber inside its body that heats up, roasting the trapped soul alive. Someone confined within has some room to move around but is completely sealed off from escape unless the door to the chamber is open from the outside. Every round the victim spends in the chamber they take 1d4 Fire damage. The victim inside is able to make attacks against the bull but has disadvantage due to the confined space.

If the Brazen Bull’s hit points drop below half and it is struck a critical hit, the chamber door malfunctions, opening up to allow the victim to escape. Someone may also attempt to open the hatch manually from the outside while standing next to the door by making a dexterity check DC 18.

Bull Rush. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 18 (4d6 + 4) piercing damage. If the target is a creature, it must succeed on a DC 14 Strength saving throw or be knocked prone.

Fire Breath (Recharge 5-6): The Brazen Bull emits a plume of fire and smoke from its nostrils in a 15-foot cone. Each creature in that area must make a DC 12 Dexterity saving throw, taking 20 (4d10) fire damage on a failed save, or half as much damage on a successful one.

Haunting Bellows. If a victim is alive and inside the heated chamber, their cries of pain travel through a series of complex tubes and vents, and are turned into a haunting refrain that emanates from the Brazen Bull’s mouth. At the start of their turn, creatures that can hear the cries must succeed on a Wisdom saving throw DC 10 or become Frightened for 1 minute. Successful saves make the creature immune to the effects.
