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

Magic Weapons. Gugalanna's weapon attacks are magical.

Trampling Charge. If Gugalanna moves at least 20 feet straight toward a creature and then hits it with a horns attack on the same turn, that target must succeed on a DC 22 Strength saving throw or be knocked prone. If the target is prone, Gugalanna can make one kick attack against it as a bonus action.

Multiattack. Gugalanna makes two attacks: one with its horns and one with its kick.

Horns. Melee Weapon Attack: +14 to hit, reach 5 ft., one target. Hit: 34 (5d10 + 7) piercing damage and 14 (4d6) fire damage.

Kick. Melee Weapon Attack: +14 to hit, reach 5 ft., one target. Hit: 18 (2d10 + 7) bludgeoning damage.

Rearing Stomp (Costs 2 Actions). Gugalanna spreads his wings and stomps his hooves, shaking the earth. Each creature within 10 feet of Gugalanna must make a DC 22 Strength saving throw. On a failure, a target takes 18 (2d10 + 7) bludgeoning damage and is pushed 20 feet away from Gugalanna. On a success, a target takes half the damage and isn't pushed. Gugalanna can then fly up to half his flying speed.

Blazing Sun Disc (Costs 2 Actions, Recharge 5-6). The sun disc floating between Gugalanna's horns flares. Each creature within 30 feet of Gugalanna must make a DC 18 Dexterity saving throw, taking 21 (6d6) fire damage on a failed save, or half as much damage on a successful one.
