Black Flame Broners A vrolikai can manifest a dagger-shaped blade of what looks like crystallized black flame in each of their four hands. These weapons function as +2 greater striking daggers, although they fade away into nothingness 1 minute after a vrolikai no longer carries them.

Consume Death [>] (concentrate, divine, necromancy, visual) The vrolikai focuses their death-stealing gaze upon a single target they can see within 30 feet. The target must immediately attempt a Fortitude save against death-stealing gaze. Success The creature is unaffected.Failure The creature is affected by deathstealing gaze and becomes drained 1. If the creature was already drained 1 by the death-stealing gaze before attempting the save, a failed save increases the value of the drained condition by 1, to a maximum of drained 4. The vrolikai gains 10 temporary Hit Points, and the drained creature is temporarily immune until the start of the vrolikai's next turn.Critical Failure As failure, but the creature increases the amount of drain by 2.

Focused Flames [>>] The vrolikai attacks a single target with all of its black flame broners. The demon makes a black flame knife Strike. On a successful attack, the vrolikai deals the damage from a black flame knife Strike to the target, plus an additional 2d6 negative damage for every black flame knife they wield beyond the first (typically 6d6 extra damage). Even on a failed attack, the vrolikai deals the damage from one black flame knife to the target, though they still miss completely on a critical failure. On a critical hit, the victim becomes drained 2 as the focused attack drains pure life essence as well as damage. This counts toward the vrolikai's multiple attack penalty as a number of attacks equal to the number of black flame broners the demon wields.

Mindwarping (emotion, enchantment, mental) The sting of a vrolikai is mind-warping. A creature struck must attempt a DC 44 Will save. Critical Success The creature is unaffected.Success The creature becomes stupefied 1 for 1 minute.Failure The creature becomes stupefied 1. Further failed saves against mindwarping increase the condition value by 1, to a maximum of stupefied 4.Critical Failure As failure, but the creature also becomes confused for 1 minute.

Stolen Death A creature that dies while suffering drain from a nabasu's death-stealing gaze rises as a ghoul (Bestiary 168) the next midnight.
