Special Traits

  • Legendary Resistance (3/Day). If the dragon fails a saving throw, it can choose to succeed instead.


  • Multiattack. The dragon makes two attacks: one with its bite and one to constrict.
  • Bite. Melee Weapon Attack: +14 to hit, reach 10 ft., one target. Hit: 19 (2d10 + 8) piercing damage.
  • Constrict. Melee Weapon Attack: +13 to hit, reach 15 ft., one Large or smaller creature. Hit: 19 (2d10 + 8) bludgeoning damage. The target is grappled (escape DC 22) if the nemeios dragon isn’t already constricting a creature, and the target is restrained until this grapple ends.
  • Fire Breath (Recharge 5-6). The dragon exhales fire in a 60- foot cone. Each creature in that line must make a DC 14 Dexterity saving throw, taking 54 (12d8) fire damage on a failed save, or half as much damage on a successful one.
  • Tail. Melee Weapon Attack: +13 to hit, reach 15 ft., one target. Hit: 18 (2d8 + 9) bludgeoning damage.

  • Tail Attack. The dragon makes a tail attack.
  • Bite (Costs 2 Actions). The nemeios dragon makes one bite attack.


This massive serpent has three rows of hooked teeth, a threefold quivering tongue, and a gilded forehead. Green spumes drips from its fangs and its eyes glitter with malevolence.

Nemeios dragons attack everything in sight, grappling and biting. These beasts are primarily found in Achaea.

Wyrmlings are sometimes raised as companions to heroes.
