Actions

Multiattack. The deathlock makes two Deathly Claw or Grave Bolt attacks.

Deathly Claw. 6 to hit, reach 5 ft., one target. Hit: 13 (3d6 + 3 necrotic damage).

Grave Bolt. 6 to hit, range 120 ft., one target. Hit: 13 (3d8) necrotic damage. If the target is Large or smaller, it must succeed on a 16 Strength saving throw or become restrained as shadowy tendrils wrap around it for 1 minute. A restrained target can use its action to repeat the saving throw, ending the effect on itself on a success.
