Sunlight Sensitivity. While in sunlight, the wight has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.

Actions

Multiattack. The wight makes two longsword attacks or two longbow attacks. It can use its Life Drain in place of one longsword attack.

Life Drain. Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 5 (1d6 + 2) necrotic damage. The target must succeed on a DC 13 Constitution saving throw or its hit point maximum is reduced by an amount equal to the damage taken. This reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0. A humanoid slain by this attack rises 24 hours later as a zombie under the wight’s control, unless the humanoid is restored to life or its body is destroyed. The wight can have no more than twelve zombies under its control at one time.

Longsword. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 6 (1d8 + 2) slashing damage, or 7 (1d10 + 2) slashing damage if used with two hands.

Keen Hearing and Smell. The wolf has advantage on Wisdom (Perception) checks that rely on hearing or smell.

Pack Tactics. The wolf has advantage on an attack roll against a creature if at least one of the wolf’s allies is within 5 feet of the creature and the ally isn’t incapacitated.

Snow Camouflage. The wolf has advantage on Dexterity (Stealth) checks made to hide in snowy terrain.

Actions

Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) piercing damage. If the target is a creature, it must succeed on a DC 14 Strength saving throw or be knocked prone.

Cold Breath (Recharge 5–6). The wolf exhales a blast of freezing wind in a 15-foot cone. Each creature in that area must make a DC 12 Dexterity saving throw, taking 18 (4d8) cold damage on a failed save, or half as much damage on a successful one. The arctic-dwelling winter wolf is as large as a dire wolf but has snow-white fur and pale blue eyes. Frost giants use these evil creatures as guards and hunting companions, putting the wolves’ deadly breath weapon to use against their foes. Winter wolves communicate with one another using growls and barks, but they speak Common and Giant well enough to follow simple conversations.
