Divining  Tongue. Strong evil registers to a devadragonet's senses like a revolting stink, while powerful good tastes like heavenly ambrosia. As an action, the devadragonet can flick its tongue and taste or smell the presence of such forces within 60 feet of it that is not behind total cover. The devadragonet knows the type (celestial, fiend, or undead) of any being it senses, but not their identity or location. Within the same radius, the dragonet also detects the presence of any place or object that has been consecrated or desecrated, as with the hallow spell.

The devadragonet can also use divination tongue on a single object or creature within 5 feet as a free action, allowing it to determine the location of the sacred or unholy presence but not its identity.

If a devadragonet scents a powerful good or evil presence (a creature of Challenge 9 or higher or a magical effect using a 5th level or higher spell slot or of at least caster level 12) its divining tongue ability is overwhelmed and cannot be used again until the presence has moved out of sense range and 1 to 3 minutes (4d6 + 6 rounds) have passed. Divining tongue is also overwhelmed when the devadragonet is affected by overpowering mundane smells or tastes such as strong perfumes, chili, or the spray of a skunk.

Keen Senses. The devadragonet has advantage on Wisdom (Perception) checks that rely on sight, hearing, or smell.

Magic Resistance. The devadragonet has advantage on saving throws against spells and other magical effects.

Multiattack. The devadragonet makes two attacks: one with its bite and one with its claws

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d4+2) piercing damage plus  1 radiant damage.​

Claws. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 3 (1d6) slashing damage.

Breath Weapons (Recharge 5-6). The devadragonet uses one of the following breath weapons.

• Heavenscent Breath (Recharge 5-6):  The devadragon exhales a puff of energised vapour at one creature within 5 feet of it.​  A target that is not a fiend or undead immediately regains 1 hit point and enters a blissful delirium for 1d4 rounds. The target may attempt to avoid the delirium by rolling a DC 11 Wisdom saving throw. While delirious, the target regains 1 hit point at the end of each round but has disadvantage on all skill checks and attack rolls. On the target's turn they can choose to leave the blissful delirium as a free action but this also stops the healing. Once a target is healed by heavenscent breath they must take a long rest before they can regain hit points from another puff, but they can still suffer disadvantage from the blissful delirium. A puff of heavenscent breath heals a maximum of 3 (1d4 + 1) hit points to individuals who receive the full 1 to 4 rounds effect.
   A target that is a fiend or undead takes 10 (3d6) damage and enters a nightmare delirium for 1d4 rounds; if the target makes a DC 11 Wisdom saving throw they take half damage and avoid entering the delirium. While delirious, the target has disadvantage on all skill checks and attack rolls. The fiend or undead target can repeat the saving throw at the end of each of its turns. If they succeed, the nightmare delirium ends.

• Radiant Breath. The devadragonet exhales a glorious beam of light at at one creature within 10 feet of it. The target must make a DC 11 Dexterity saving throw or take 10 (3d6) radiant damage and be blinded for 1 minute; if they save successfully they take half damage and are not blinded. A creature can repeat the saving throw at the end of each of its turns, ending the blindness effect on itself on a success. Radiant breath does no damage to celestial creatures but can still blind them.
