Horrifying Visage. When a creature that can see the lantern starts its turn within 30 feet of the lantern, the lantern can force it to make a DC 14 Wisdom saving throw if the lantern isn't incapacitated. On a failed save, a creature takes 13 (3d10) psychic damage and is frightened until the end of its next turn. On a successful save, the creature takes half as much damage and isn't frightened.
Unless surprised, a creature can avert its eyes to avoid the saving throw at the start of its turn. If the creature does so, it can't see the lantern until the start of its next turn, when it can avert its eyes again. If the creature looks at the lantern in the meantime, it must immediately make the save.
Multiattack. The lantern makes one attack with its tentacles. If that attack hits, the lantern can make one bite attack against the same target.
Tentacles. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 7 (1d10 + 2) bludgeoning damage and the target is grappled (escape DC 12).
Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) piercing damage.
Ethereal Song (Recharge 6). The lantern emits a haunting melody audible to 120 feet. Each creature that can hear the melody must make a DC 14 Wisdom saving throw, taking 13 (3d8) psychic damage on a failed save, or half as much damage on a successful one.
Winter lanterns are horrific creatures from a far off, unknowable plane. It is unknown how they end up found across the lands, but rumors suggest they spawn forth when a mother kills their child in cold blood. Those who have encountered a winter lantern and survived know not to look directly at one, as just witnessing its terrible form can cause irreversible harm.
The winter lanterns appear as tall, humanoid creatures with a huge, writhing mass of eyes and tentacles for a head. The humanoid lower half of the creature almost always appear to be of female human or elven origin, donning very basic robes that are always drenched in a blood-like liquid. The winter lantern's nightmarish head is covered in eyes of various shapes and sizes. All of the eyes are staring, yet seem to not actually perceive at which they stare. Hidden within the head of the creature, there are also long tentacles and multiple mouths filled with razor sharp teeth. The winter lantern will conceal these appendages until a target is within range of them.
The winter lantern's tell that one is near is a soft, hummed song which all of them seem to know. The ethereal song sounds as though it is being hummed right into your ear, yet can be heard anywhere within a great distance surrounding the creatures.
