The hide of a demon lays just beneath the surface of your skin, itching with every good deed you witness and urging you to act with the same despicable malevolence as the creature that it once belonged to. You gain the following benefits and flaw:
- You gain natural armor that increases your AC by 1.
- You may spend a reaction to gain advantage on a Strength, Dexterity, or Constitution saving throw. You may use this ability a number of times equal to your proficiency bonus, and regain all uses by completing a long rest.

this isnt anything special but it isnt that bad
This ain't good enough to justify the voices in my head, chief.
The first part claims there's a flaw, but I don't see any flaw.
I get it's nothing amazing, but for second-most downvoted feat it's honestly decent. Perfectly solid, can't just be replicated with another feat or an ASI, and some interesting flavour text.
Decently balanced, just bland
the effect doesn't really have much to do with the flavor. honestly way too plain of an effect for having demon skin under your own skin. And where's the flaw? it says there's a flaw
This is nice but there is no flaw to the demon inside you
