SPECIAL TRAITS

  • Spellcasting. The naga is a 10th-level spellcaster. Its spellcasting ability is Intelligence (spell save DC 14, +6 to hit with spell attacks), and it needs only verbal components to cast its spells. It has the following wizard spells prepared:
    • Cantrips (at will): mage hand, minor illusion, ray of frost
    • 1st level (4 slots): alarm, charm person, identify
    • 2nd level (3 slots): detect thoughts, bottled dread (page 33)
    • 3rd level (3 slots): dispel magic, lightning bolt, vampiric touch
    • 4th level (3 slots): dark abyss (page 34), fire shield
    • 5th level (2 slots): dominate person, planar binding
  • Spiteful Rejuvenation. If it dies, the naga returns to life in 1d6 days and regains all its hit points. Only a wish spell can prevent this trait from functioning. It knows the distance and direction to the creature that last killed it.

ACTIONS

  • Bite. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 7 (1d6 + 4) piercing damage, and the target must make a DC 13 Constitution saving throw, taking 31 (7d8) poison damage on a failed save, or half as much on a successful save.

REACTIONS

  • Vengeful Retaliation. When the naga is reduced to 0 hit points, it makes a weapon attack before dying. If this attack is made against the creature that reduced the naga to 0 hit points, the naga makes this attack with advantage. The naga then dies.

ABOUT

This large serpent has dark, mottled skin and a hateful glare. Its skin is marred with glowing red scars.

Spiteful creatures that crave power, spirit nagas are quick to pretend to prostrate themselves before the fiends of the Cocytus legion as soon as they believe there are fiendish secrets and minions to be gained. Unfortunately for these ersatz devotees, the fiends are quick to corrupt and force the nagas into their service. Corrupted spirit nagas primarily serve the fiends as arcane support; when not actively serving their fiendish masters, they research how to escape their ill-advised bargain.

Cocytus Corruption

Patient hunters in caverns and caves, ropers rarely interact with other creatures except to ambush them with strength-draining tendrils. Fiends are generally impatient and rapacious, but canny leaders understand the value that a watchful guardian brings to their forces. Many legions therefore intentionally recruit ropers, promising an unending bounty of victims and treasure. The Cocytus legion typically corrupts ropers to watch over underground fortresses or even stranger domains, where the corrupted ropers surprise intruders with weakening tendrils that make other fiends better able to inflict their vengeance.

Cocytus corruption grants the Vengeful Retaliation reaction.

Vengeful Retaliation. When the Cocytus-corrupted creature is reduced to 0 hit points, it makes a weapon attack just before dying. If this attack is made against the creature that reduced the corrupted creature to 0 hit points, the corrupted creature makes this attack with advantage. The corrupted creature then dies.
