Bestiary 4 | Monsters | Seaweed Siren | Special Abilities | False Heads
A
seaweed siren's
false heads can be severed. To sever a head, an opponent must make a sunder attempt with a slashing weapon
targeting the head. A head is considered a
separate weapon with hardness 0 and hit points equal to the
siren's Hit Dice (typically 16 hp). To sever a head, an opponent must deal enough damage to reduce the head's hit points to 0 or fewer. Severing a head deals an amount of damage to the
siren's body equal to the
siren's Hit Dice. A
siren can't attack with a severed head. A
siren with no remaining heads can't use its
cacophony ability or its
spell-like abilities.
