Innate Spellcasting. The couatl's spellcasting ability is Charisma (spell save DC 14). It can innately cast the following spells, requiring only verbal components:
At will: detect evil and good, detect magic, detect thoughts
3/day each: bless, create food and water, cure wounds, lesser restoration, protection from poison, sanctuary, shield
1/day each: dream, greater restoration, scrying
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.
Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one creature. Hit: 8 (1d6 + 5) piercing damage, and the target must succeed on a DC 13 Constitution saving throw or be poisoned for 24 hours. Until this poison ends, the target is unconscious. Another creature can use an action to shake the target awake.
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.
Change Shape. The couatl magically polymorphs into a humanoid or beast that has a challenge rating equal to or less than its own, or back into its true form. It reverts to its true form if it dies. Any equipment it is wearing or carrying is absorbed or borne by the new form (the couatl's choice).
In a new form, the couatl retains its game statistics and ability to speak, but its AC, movement modes, Strength, Dexterity, and other actions are replaced by those of the new form, and it gains any statistics and capabilities (except class features, legendary actions, and lair actions) that the new form has but that it lacks. If the new form has a bite attack, the couatl can use its bite in that form.
As you can read at the top it's lawful good so it won't do anything inherently bad
Just a thought on how to play these with another creature.
I'm running this into a mini boss fight with 6 couatls and an empyrean (my 4 players are formidable and at lvl 16 respectively) I'm going to use the empyrean to tank and use the couatl to buff and heal him until he has dealt with the AoE caster and the DPS spell caster to make it a memorable fight. I still highly believe they will prevail but it has been a while since they had a serious challenge. I will come back and post how it goes.
My reaction exactly like this might not be the BEST creature but dude it's freaking awesome and I love couatls!
You can summon this for Conjure Celestial!? I didn't know that. thank you for the info 😁
funny snake
I managed to pull the moon card from the deck of many things and wished that (as a druid) I could wild shape into celestials so now I'm able to Wild shape into this at level 12. Seriously this is OP as it can Polymorph for 12 hours a day I have infinite Polymorphs, can talk telepathically and as I have a tattoo of Spirit leach can do an extra 4d6 to all damage I do. Best character yet!
