Spirit Naga

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): charm person, detect magic, sleep
2nd level (3 slots): detect thoughts, hold person
3rd level (3 slots): lightning bolt, water breathing
4th level (3 slots): blight, dimension door
5th level (2 slots): dominate person

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

Melee Weapon Attack: +7 to hit, reach 10 ft.. Hit: 7 (1d6 + 4) piercing damage.
The target must make a DC 13 Constitution saving throw, taking 24 (7d6) poison damage on a failed save, or half as much damage on a successful one.
