Actions
Multiattack. The nagpa makes three Staff or Deathly Ray attacks. It can replace one attack with a use of Spellcasting.
Staff. 8 to hit, reach 5 ft., one target. Hit: 9 (2d6 + 2) bludgeoning damage plus 24 (7d6) necrotic damage.
Deathly Ray. 12 to hit, range 120 ft., one target. Hit: 30 (7d6 + 6) necrotic damage.
Bonus Actions
Corruption. The nagpa targets one creature it can see within 90 feet of it. The target must make a 20 Charisma saving throw. An evil creature makes the save with disadvantage. On a failed save, the target is charmed by the nagpa until the start of the nagpa's next turn. On a successful save, the target becomes immune to the nagpa's Corruption for the next 24 hours.
Paralysis (Recharge 6+). The nagpa forces each creature within 30 feet of it to make a 20 Wisdom saving throw, excluding Undead and Constructs. On a failed save, a target is paralyzed for 1 minute. A paralyzed target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
