Death's Head of Bhaal

As long as the death's head is not incapacitated, hostile creatures within 5 feet of it gain vulnerability to piercing damage unless they have resistance or immunity to such damage.

The death's head has advantage on saving throws against spells and other magical effects.

The death's head uses Stunning Gaze and makes two dagger attacks.

Melee or Ranged Weapon Attack: +7 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 7 (1d4 + 5) piercing damage.

The death's head targets one creature it can see within 30 feet of it. The target must succeed on a DC 14 Wisdom saving throw or be stunned until the end of its next turn.

The death's head reduces the damage it takes from an attack to 0.
