Betirran the Cruel

Nimble Thunder. Betirran has advantage on all dexterity checks and saving throws.

Cruelty Incarnate. Betirran has advantage on attack rolls against creatures frightened of her.

Legendary Resistance (2/day). When Betirran fails a saving throw, she can choose to succeed instead.

Multiattack. Betirran uses her Frightful Presence. She then makes one attack with her bite or two cruelty bolt attacks.

Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: Deals 15 (2d10 + 4) piercing damage plus 3 (1d6) lightning damage.

Frightening Presence. Each creature of Betirran’s choice that is within 120 ft. of Betirran and aware of her must succeed on a DC 16 Wisdom saving throw or become 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 Betirran’s Frightful Presence for the next 24 hours.

Cruelty Bolt. Ranged Weapon Attack: +8 to hit, range 60/120 ft., one target. Hit: Deals 9 (1d10 + 4) lightning damage and the target must succeed on a DC 16 Wisdom saving throw or be frightened of Betirran until the end of her next turn.

Lightning Breath (Recharge 5-6). The dragon exhales lightning in an 60-foot line that is 5 feet wide. Each creature in that line must make a DC 16 Dexterity saving throw, taking 33 (6d10) lightning damage on a failed save, or half as much damage on a successful one. 

Cruel Cunning. When a creature Betirran can see makes a ranged attack roll, she can make a cruelty bolt attack against that creature. If she damages the target, their attack roll misses.
