Burst of Flight. The reef viper can fly in short bursts. When it moves, it can fly up to it's flying speed on its turn, but it falls to the ground if it is still in the air after its movement ends.


Bite. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 11 (2d6 + 4) piercing damage.

Constrict. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 13 (2d8 + 4) bludgeoning damage, and the target is grappled (escape DC 14). Until this grapple ends, the creature is restrained, and the snake can't constrict another target.

Bile Sac (Recharge 5-6). The reef viper spits out acid in a 15-foot cone. Each creature in that area must make a DC 12 Agility saving throw, taking 21 (6d6) acid damage on a failed save, or half as much on a successful one.

Found In: Bestiary of Summerset


The large and deadly reef vipers are cunning predators that can be found stalking along the beaches of Summerset.

Hostile Pests. These winged serpents are treated as vicious vermin—an invasive species brought to the isles by the Sea Elves. The Maormer bring them to the coasts as a means of goading the Altmer and disrupting the natural habitats of Summerset.

Venomous Hunters. Reef vipers are giant, stout snakes with large wingspans, allowing them to fly short bursts. Combined with their razor sharp teeth, these creatures are made from ophidiophobic nightmares. They like to get up close to their opponents and use their internal bile sac to produce a sticky fluid to aid in catching and digesting the serpent's prey.
