Anjanath/Fulgur Anjanath

Brute Wyvern. Anjanath has advantage on Strength and Constitution saving throws.

Subspecies. Fulgur Anjanath is a type of Anjanath known for its alternate coloring and stripes. If you wish to use Fulgur Anjanath as a monster, replace all Fire damage with Lightning Damage.

Multiattack. The Anjanath makes two Bite attacks, or two Tail Slap attacks, or one Bite and one Tail Slap attack. However, if you choose the third option, you must use the second attack on a creature on the opposite side of the Anjanath, as the Anjanath would have to spin quickly in order to hit one creature with both attacks.

Bite. Melee Attack: +12 to hit, reach 5 ft., 1 target. Hit: 27 (5d8+7) piercing damage and (4d8) fire damage if enraged.

Tail Slap. Melee Attack: +12 to hit, reach 5 ft., 1 target. Hit: 23 (4d8+7) bludgeoning damage and the recipient is knocked back five feet to the left or right (DM's choice).

Fire Breath (Recharge 6). All creatures in a line 60 feet long and 15 feet wide must make a Dexterity saving throw DC 17 or take (12d8) fire damage. Creatures that succeed the saving throw only take half damage.

Bulldoze (Recharge 6). The Anjanath charges up to 40 feet. in a single direction while using its head like a bulldozer. Any creature in the path of this attack must roll a Dexterity saving throw DC 17. On a failed save, the creature takes (6d8) force damage, and is pushed by the Anjanath to a space 10 feet away from the Anjanath's ending position. On a successful save, the creature takes no damage and is not pushed. If a creature succeeds and is in the Anjanath's space, you can move them to the nearest unnocupied space or allow to stay in the Anjanath's space.

Frightful Prescence (4-6). Each creature of the Anjanath's choice that is within 120 feet of the Anjanath and aware of it must succeed on a DC 17 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 the Anjanath's Frightful Presence for the next 24 hours.

The Anjanath has 3 legendary actions. It can use only one at the end of a creature's turn.

Bite (Costs 1 action). The Anjanath uses its Bite attack.

Leap (Costs 2 actions). The Anjanath leaps to an open space up to 30 feet away.

Burning Rage. When the Anjanath reaches 50%, its nose and spines flare up, and its attacks do additional fire/lightning damage (detailed in attacks).
