Couatl Scorned (5e Creature)
From D&D Wiki
Medium undead, chaotic evil
Damage Resistances necrotic
Innate Spellcasting. The couatl's spellcasting ability is Charisma (spell save DC 12). It can innately cast the following spells, requiring only verbal components:
Magic Weapons. The couatl's weapon attacks are magical.
Shielded Mind. The couatl is immune to scrying and to any effect that would sense its emotions, read its thoughts, or detect its location.
Constrict. Melee Weapon Attack: +6 to hit, reach 10 ft., one Medium or smaller creature. Hit: 10 (2d6 + 3) bludgeoning damage, and the target is grappled (escape DC 15). Until this grapple ends, the target is restrained, and the couatl can't constrict another target.
Couatl scorned are creatures that look like couatls, but their scales and feathers are dull. They are crafted from shadow, and held together by rituals that require the scales of a true couatl.
