Shapechanger. The wereagle can use its action to polymorph into an eagle-humanoid hybrid or into Medium eagle, or back into its true form, which is humanoid. Its statistics are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Innate Spellcasting (Humanoid or Hybrid Form Only). The wereagle's innate spellcasting ability is Wisdom (spell save DC 12). The wereagle can innately cast the following spells, requiring no material components:

At will: light, sacred flame, thaumaturgy
2/day each: augury, daylight, detect evil and good, detect poison and disease, prayer of healing
1/day: freedom of movement

Keen Sight. The wereagle has advantage on Wisdom (Perception) checks that rely on sight.

Multiattack (Hybrid Form Only). The wereagle makes two attacks with its talons, or one attack with its beak and one attack with its talons.

Beak (Eagle or Hybrid Form Only). Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) piercing damage. If the target is a humanoid, it must succeed on a DC 11 Constitution saving throw or be cursed with wereagle lycanthropy.

Talons (Eagle or Hybrid Form Only). Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (2d4 + 3) slashing damage.

Sacred Flame (Cantrip, Humanoid or Hybrid Form Only). Flame-like radiance descends on a creature that the wereagle can see within 60 feet. The target must succeed on a DC 12 Dexterity saving throw or take 9 (2d8) radiant damage. The target gains no benefit from cover for this saving throw.
