Actions

Multiattack.

Hjoldak makes two Necrotic Shard attacks. It also uses Psionic Crown if available.

Necrotic Shard.

Melee or Ranged Attack Roll: +7 to hit, reach 5 ft. or range 60 ft., one target. Hit: 7 (1d6 + 4) piercing damage plus 9 (2d8) necrotic damage. If the target is a creature, it has disadvantage on the next attack roll it makes before the end of its next turn.

Psionic Crown (Recharge 5-6).

Hjoldak wreathes the head of a creature it can see within 60 feet of itself with a crown of jagged, spectral crystals. The target must succeed on a DC 14 Wisdom saving throw or have the charmed condition for 1 minute. While charmed in this way, the target's thoughts are sluggish; it can't take reactions, its speed is halved, and it takes 9 (2d8) psychic damage at the start of each of its turns. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Spellcasting (Psionics)

Hjoldak casts one of the following spells, requiring no spellcasting components and using Intelligence as the spellcasting ability (spell save DC 14):

At will: mage hand (the hand is invisible)

1/day: calm emotions
