  • Rain Frenzy. Adaros revere storms, and their lust for blood is amplified exponentially while it is raining. While fighting in the rain or during other stormy weather, adaros have advantage on Strength saving throws and saving throws against being frightened. In such conditions, at the start of its turn, the adaros can gain advantage on all melee weapon attack rolls during that turn, but attack rolls against it have advantage until the start of its next turn. An adaro gains this benefit even if it is underwater, but only as long as it remains within one turn away from the water’s surface.
  • Speak with Sharks. An adaro can communicate telepathically with sharks to a distance of 100 feet. This communication is limited to simple concepts, such as “come,” “defend,” or “attack.”
  • Water breathing. The adaro can only breathe underwater.


  • Underwater Rage (3/day). An adaro can enter a rage while underwater. While in this rage, they deal an extra 4 (1d8) damage whenever they make a successful attack against a creature, but they have disadvantage on all Wisdom and Intelligence saving throws. This rage lasts 1 minute, until ended as a bonus action, or the adaro does not attack a creature nor take damage in a turn.


  • Multiattack. The adaro makes two bite attacks.
  • Bite. Melee Weapon Attack: +4 to hit, 5 ft. reach, one target. Hit: 12 (2d8 + 3) piercing damage.


Malevolent denizens of the waters, adaros are among the fiercest sentient hunters of the tropical seas. They are known and feared by sailors on many exotic shores, as well as by common folk who just happen to live near the ocean. Many have witnessed a fellow sailor or fisher suddenly go rigid, a poisoned spear jutting from his guts, only to fall into the water and be taken by the vicious adaro responsible for the assault.

Strictly carnivorous, adaros feed upon their victims almost immediately after slaying them. Their brutally sharp teeth cut through bone almost as easily as through flesh, and their powerful digestive systems are capable of handling most organic matter. Adaros usually eat once every couple of days, gorging on meals half their weight.

Adaros’ strange relationship with storms has intrigued scholars for centuries. These sea-dwellers have a special connection to the deadly creatures of the water and the wildness of foul weather, and it is no coincidence that they attack humanoids more often during rough seas. Adaros are seminomadic by nature; a tribe travels until it finds a suitable hunting ground and leaves either when its presence becomes too well known or when its game runs low.

An adaro is 7-1/2 feet long and weighs 250 pounds.
