Caelithorne, the Bloodhorn Unicorn

Runes of Fire & Wrath. Caelithorne’s attacks count as magical.

Aura of Flame. Any enemy that starts its turn within 5 feet of Caelithorne takes 5 fire damage.

Rune Reversal (1/day). When Caelithorne is targeted by a spell of 3rd level or lower, it can use its reaction to automatically counterspell the effect.

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

Multiattack. Caelithorne makes two attacks: one with its hooves and one with its horn.

Hooves. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 5) bludgeoning damage plus 7 (2d6) fire damage.

Bloodhorn (Horn). Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 5) piercing damage plus 7 (2d6) fire damage.

Flarehorn Charge (Recharge 5–6). If Caelithorne moves at least 20 feet straight toward a target and then hits it with a Bloodhorn attack on the same turn, the target takes an extra 14 (4d6) piercing damage. Additionally, the target is affected by Hellish Rebuke (cast at 2nd level, DC 14).

Ignite Horn (Recharge 4–6). Caelithorne wreathed its horn in flame until the end of its turn. Its next Bloodhorn attack deals an additional 10 (3d6) fire damage.

Flame Step. Caelithorne magically teleports up to 30 feet to an unoccupied space it can see, leaving behind a burst of flame. Each creature within 5 feet of the space it left must make a DC 14 Dexterity saving throw, taking 7 (2d6) fire damage on a failed save, or half as much on a success.

Rune Reversal (1/day). (already included) – Auto-counter a spell of 3rd level or lower.

Fiery Vengeance. When a creature within 10 ft. hits Caelithorne with a melee attack, it can unleash a burst of flame. The attacker must succeed on a DC 14 Dexterity saving throw or take 9 (2d8) fire damage.

Horn Parry. When a creature Caelithorne can see makes a melee attack roll against it, Caelithorne adds +3 to its AC against that attack. If the attack misses, the attacker takes 5 piercing damage from a deflecting jab of the horn.
