Legendary Resistance (3/Day). If Iðunn fails a saving throw, she can choose to succeed instead.
Multiattack. Iðunn can use her Mournful Presence. She then makes three attacks: one with her bite and two with her claws.
Bite. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 17 (2d10 + 6) piercing damage plus 3 (1d6) fire damage.
Claw. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 13 (2d6 + 6) slashing damage.
Tail. Melee Weapon Attack: +10 to hit, reach 15 ft., one target. Hit: 15 (2d8 + 6) bludgeoning damage.
Razing Breath (Recharge 5–6). Iðunn exhales cursed fire in a 30-foot cone. Each creature in that area must make a DC 17 Dexterity saving throw, taking 56 (16d6) fire damage on a failed save, or half as much damage on a successful one.
Mournful Presence. Each creature of Iðunn's choice that is within 120 feet of her and aware of her must succeed on a DC 24 Wisdom saving throw or become overwhelmed by feelings of despair. The creature becomes frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to Iðunn's Mournful Presence for the next 24 hours.
Dragon God's Insight (3/Day). When Iðunn or a creature she can see makes an attack roll, a saving throw, or an ability check, Iðunn can cause the roll to be made with advantage or disadvantage.
Iðunn can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. Iðunn regains spent legendary actions at the start of her turn.
Detect. Iðunn makes a Wisdom (Perception) check.
Tail Attack. Iðunn makes a tail attack.
Wing Attack (Costs 2 Actions). Iðunn beats her wings. Each creature within 15 feet of Iðunn must succeed on a DC 25 Dexterity saving throw or take 17 (2d6 + 10) bludgeoning damage and be knocked prone. Iðunn can then fly up to half her flying speed.
Description
The lost oracle of the Dragonkin. Dark, malevolent energy washes off of her in waves, fueled by her grief and loneliness.
