Spellcasting. The vault naga is a 9th-level spellcaster. Its spellcasting ability is Wisdom (spell save DC 14, +6 to hit with spell attacks), and it needs only verbal components to cast its spells. It has the following cleric and paladin spells prepared:

  • Cantrips (at will): guidance, sacred flame, thaumaturgy
  • 1st level (4 slots): bless, cure wounds, divine favor, shield of faith*
  • 2nd level (3 slots): branding smite, hold person, spiritual weapon
  • 3rd level (3 slots): dispel magic, meld into stone, spirit guardians
  • 4th level (3 slots): banishment, freedom of movement*, guardian of faith
  • 5th level (1 slot): flame strike

*The vault naga casts these spells on itself before combat.

Brutal Swing. The vault naga can reroll any of the damage die for its tail axe if the roll is 1 or 2. It must use the new roll.

Magic Weapons. The vault naga’s weapon attacks are magical.

Rejuvenation. If it dies, the vault naga returns to life in 1d6 days and regains all its hit points. Only a wish spell can prevent this trait from functioning.


Multiattack. The vault naga makes two attacks, one with its bite and one with its tail axe.

Bite. Melee Weapon Attack: +8 to hit, reach 10 ft., one creature. Hit: 9 (1d8 + 5) piercing damage plus 27 (6d8) poison damage. The target must make a DC 14 Constitution saving throw, taking the poison damage on a failed save, or half as much damage on a successful one.

Tail Axe. Melee Weapon Attack: +8 to hit, reach 10 ft., one creature. Hit: 15 (3d6 + 5) slashing damage.
