Amphibious. The yaghra larva can breathe air and water.

Pheromone Rage. The yaghra larva prefers to attack creatures that have been marked with pheromones by a yaghra spewer's Luminescent Mark action. Any attacks made against a marked creature are made with advantage.

Suicidal Burst. When the yaghra larva is reduced to 5 hit points or less, it uses the Explosive Toxins action on its next action. Once it uses this action, its hit points are immediately reduced to 0 and it dies.


Acid Discharge. Ranged Spell Attack: +3 to hit, range 30/30 ft., one target. Hit: 5 (1d10) acid damage.

Pierce. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 6 (2d4 + 1) piercing damage.

Explosive Toxins (Special). The yaghra larva swells and explodes. Each creature within a 15-foot radius must make a DC 11 Agility saving throw, taking 3 (1d6) acid damage and 3 (1d6) piercing damage on a failed save, or half as much on a successful one.

Found In: Bestiary of Summerset


Yaghra are fantastic, deep sea creatures that live in Nirn's many oceans and seas. The extent of the yaghra's spread across the world is generally unknown and they have no known names to surface-dwellers.

These crustacean creatures are protected by their chitinous carapaces, spikes, and strange internal biology. They are strongly influenced by pheromones and appear to communicate through their chemical physiology, sometimes regurgitating their stomach acids. The different forms of yaghra that have appeared throughout Tamriel may be unique breeds, or different morphologies of the same life cycle.

Yaghra Larva

The young yaghra larva are spider-like bottom feeders. They have six legs and a volatile, enlarged abdomen. The larva tries to keep enemies at bay by ejecting acidic bile at their foes. These fragile creatures instinctually self-dispose of themselves when under extreme duress. They explode in a violent display of acid, bile, and chitinous spikes.
