D&D 3.0: Tales from Mystara
Horn of the Tritons
This device is a conch shell that can be blown once per day (except by a triton, who can sound it three times per day). A horn of the tritons can do any one of the following functions when blown:
Calm rough waters in a one-mile radius. This dispels a summoned water elemental if it fails its Will saving throw (DC 16).
Attract 5d4 Large sharks (a 01 – 30 result on d%), 5d6 Medium-size sharks (31 – 80), or 1d10 sea lions (81 – 100) if the character is in a body of water in which such creatures dwell. The creatures are friendly and obey, to the best of their ability, the one who sounded the horn.
Panic and demoralize aquatic creatures with Intelligence scores of 1 or 2 within 500 feet as if they had been targeted by a fear spell (DC 16). Those who do save are shaken for 3d6 rounds.
Any sounding of a horn of the tritons can be heard by all tritons within a three-mile radius.
