Couatl Herald's Scales (Patreon)

Armor (scale mail), rare (requires attunement by a creature of good alignment)

This enchanted armor is made from couatl scales that were collected by a generous celestial. You gain a +1 bonus to AC while you wear this armor. This armor does not impose disadvantage on Dexterity (Stealth) checks.

Tooth and Scale. When you take damage from a creature within 10 feet of you, you can use your reaction to channel the good spirit within the armor and cause a bright, spectral couatl to appear above you. The spectral form strikes at the creature who damaged you, forcing it to make a DC 15 Dexterity saving throw. On a failure, the creature takes 4d10 radiant damage, or half as much damage on a success. Once this property of the armor has been used, it can't be used again until the following dawn.

Flight of the Couatls. While you're attuned to 3 items with this feature, you gain a flying speed of 30 feet. If you already have a flying speed, this speed is in addition to your existing flying speed.

The Couatl were our divine protectors. They were calm amidst the din of our kind. What can we offer them in return for their service and sacrifice other than our best?
