Draconic Devotion. While Red Ruin can see a Dragon that isn't hostile to her, she has advantage on attack rolls.

Mounted Combat Master. When Red Ruin is mounted and a creature targets her mount with an attack, Red Ruin can cause the attack to target her instead.

Mounted Evasion. When Red Ruin or her mount makes a Dexterity saving throw to take half damage from an effect, they take no damage on a success and half damage on a failure.

Multiattack. Red Ruin makes three Ember Lance attacks.

Ember Lance. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit:10 (1d12 + 4) piercing damage plus 7 (2d6) fire damage. If the target is a Medium or smaller creature, it must succeed on a DC 16 Strength saving throw or fall prone.

Explosive Hand Crossbow (Recharge 5–6). Red Ruin fires an explosive crossbow bolt at a point she can see within 120 feet of herself. When the bolt reaches that point, or if it hits an object early, it detonates in a 20-foot-radius sphere. Each creature in that area must make a DC 15 Dexterity saving throw, taking 35 (10d6) fire damage on a failed save, or half as much damage on a successful one.
