Book of Ebon Tides (p.172)
Devil’s Sight. Magical darkness doesn’t impede the devil’s darkvision. Light Incorporeality. The devil is semi-incorporeal when standing in moonlight and is immune to all nonmagical attacks in such conditions. Even when hit by spells or magic weapons, it takes only half damage from a corporeal source, with the exception of force damage. Holy water can affect the devil as it does incorporeal undead. Magic Resistance. The devil has advantage on saving throws against spells and other magical effects.
Multiattack. The devil makes one Bite attack, one Claw attack, and one Tail attack. Alternatively, it can use Hurl Moonlight twice. Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) piercing damage. Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 9 (2d4 + 4) slashing damage. Tail. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 7 (1d6 + 4) bludgeoning damage. Hurl Moonlight. Ranged Spell Attack: +5 to hit, range 120 ft., one target. Hit: 11 (2d10) cold damage, and the target must succeed on a DC 13 Constitution saving throw or become blinded until the end of the devil’s next turn. Invisibility. The devil magically turns invisible until it attacks or until its concentration ends (as if concentrating on a spell). Any equipment the devil wears or carries is invisible with it.
Light Step. The devil teleports, along with any equipment it is wearing or carrying, up to 80 feet to an unoccupied space (in moonlight) it can see.
