Cuāuhpōhualli, The Eagle of Reckoning

Dive Attack. If Cuāuhpōhualli is flying and dives at least 30 feet straight toward a target and then hits it with a melee attack, the attack deals an extra 3 (1d6) damage to the target.

Fiery Incorporeality (3/day). By using an action, Cuāuhpōhualli makes himself Incorporeal for one minute. He gains the ability to move through other creatures and objects as if they were difficult terrain. Any creature that touches or hits him with a melee attack while within 5 feet of him takes 7(2d6) fire damage. However, he takes 5 (1d10) force damage if he ends his turn inside an object.

Multiattack. Cuāuhpōhualli makes two attacks, one with his Macuahuitl and one with his talons.

Macuahuitl. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) radiant damage plus 3(1d6) fire damage.

Talons. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (1d8 + 3) slashing damage plus 2(1d4) fire damage.

Death Wistle(Recharge 5-6). As an action, Cuāuhpōhualli's Death Whistle emits a haunting and dissonant melody that taps into the fears of those who hear it. All creatures of Cuāuhpōhualli's  choice within a 15 feet must make a Wisdom saving throw (DC 13) or become frightened for 1 minute. A frightened creature can repeat the saving throw at the end of each of its turns, ending the effect on itself with a success. Additionally, creatures that fail the first saving throw take 10(3d6) psychic damage and have disadvantage on their next attack roll.

Eagle's Precision. As a bonus action, Cuāuhpōhualli focuses on a target, gaining advantage on their next attack roll against a creature they can see.

Feathered Shield (Recharge 4-6). As a reaction, Cuāuhpōhualli raises his ceremonial feathered shield, gaining a +2 bonus to AC until the start of their next turn.
