Traits

Devil's Sight

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

Innate Spellcasting

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

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.

Lightwalking

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.

Magic Resistance

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

GM Tips: Using Lunar Devil

4 tips available

When using Lunar Devil in your D&D 5e campaign, consider these tactical approaches:

Flight Control Strategy: Target flying creatures with spells like 'Hold Person', 'Web', or 'Grease' to ground them. Without flight restriction, they can escape melee range easily. Consider area denial spells below their flight altitude to force them into disadvantageous positions.
Cold Damage Strategy: Cold-based attacks can slow or freeze. Prepare 'Heat Metal' or fire spells as countermeasures. Ice terrain can be used to create difficult terrain for melee characters.
Telepathic Communication: This creature can communicate telepathically, making it excellent for coordination with allies. Silence spells won't stop its communication. Consider 'Mind Blank' or abilities that block telepathy.
Incorporeal Movement: This creature can pass through objects and walls! Use 'Magic Circle', 'Forcecage', or other magical barriers. Physical obstacles are ineffective.

When your party encounters this creature, keep these strategies in mind:

Cold Damage Protection: This creature deals cold damage! Get cold resistance or use fire spells. Avoid water surfaces - they can freeze and create difficult terrain. 'Heat Metal' can counter cold.
Telepathy Awareness: This creature communicates telepathically! It can coordinate with allies silently. Silence won't stop it. Use 'Mind Blank' or abilities that block telepathy. Be cautious of mental attacks.
