Bayle, the Dread

Legendary Resistance (4/Day). If Bayle fails a saving throw, it can choose to succeed instead.

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

Magic Weapons. Bayle's weapon attacks are magical, and its Dreadfire Breath ignores resistance to fire damage.

Dreadlord. So twisted and corrupted is the cannibalistic Dreadlord, that even their very soul is divorced from its former glory. Bayle cannot be compelled by any magical means to act against how it would normally wish to act, such as by the suggestion spell.

Multiattack. Bayle makes three attacks: one with its Dreadfire Breath and two with its Wing Spike.

Dreadfire Breath. Bayle blasts out a jet of dreadfire and crimson lightning. This can be in either a 20ft radius circle centered on Bayle, a 60ft cone, or a 90ft long, 5ft wide line. Either way, all creatures within the area must make a DC 23 Dexterity saving throw, taking 33 (6d10) fire damage and 33 (6d10) lightning damage on a failed save, or half as much on a successful one.

Wing Spike. Melee Weapon Attack: +17 to hit, reach 10 ft., one target. Hit: 23 (4d6 + 9) piercing damage.

Flight of the Dreadlord (Recharge 6). Summoning the echos of wings once had, Bayle flies into the air, travelling its full movement speed before landing again, without provoking opportunity attacks. Each creature within 120ft of it at any point during its flight must succeed on a DC 23 Dexterity saving throw or take 33 (6d10) fire damage. This ignores cover. When Bayle lands, all creatures within 5ft of Bayle must make a DC 23 Strength saving throw. On a failed save, they take 23 (4d6 + 9) piercing damage, 28 (8d6) fire damage and are knocked prone. On a successful save, they take half as much damage and are not knocked prone.

Bayle can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. Bayle regains spent legendary actions at the start of its turn.

Bite. Melee Weapon Attack: +17 to hit, reach 10 ft., one target. Hit: 31 (4d10 + 9) piercing damage.

Tail. Melee Weapon Attack: +17 to hit, reach 15 ft., one target. Hit: 27 (4d8 + 9) piercing damage.

Wing of the Dreadlord (Costs 2 Actions). Bayle makes a Wing Spike attack at a target they can see within range. If they hit, the attack does an additional 28 (8d6) fire damage.
