The helmets are magic items called wolf helms. If a creature wears one of the helmets and is not a lycanthrope, they are overcome with bloodlust. The creature must succeed on a DC 15 Wisdom Save or attack the closest creature to them (except wolves and werewolves, in which case they attack the next-closest creature). The creature may attempt this save at the end of each following round to resist the urge to attack. As an action, they may attempt the same save to remove the helm. Remove curse also allows the creature to remove the helm.

In addition to its curse, each wolf helm provides a +1 AC and darkvision out to 120 feet.
