Lunar Devil

Magical darkness doesn't impede the devil's darkvision.

The devil's innate spellcasting ability is Charisma (spell save DC 15). It can innately cast the following spells, requiring no material components:

• At will: fly, major image, planar binding
• 3/day: greater invisibility
• 1/day: wall of ice

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.

Once per round, the lunar devil magically teleports, along with any equipment it is wearing or carrying, from one beam of moonlight to another within 80 feet. This relocation uses half of its speed.

The devil has advantage on saving throws against spells and other magical effects.

Summon Devil (1/Day): The devil can attempt a magical summoning. The devil has a 40 percent chance of summoning either 2 chain devils or 1 lunar devil.

The devil makes three attacks: one with its bite, one with its claws, and one with its tail. Alternatively, it can use Hurl Moonlight twice.
