In D&D 5E, the Rogue has the eponymous Reliable Talent (any roll of 9 or lower counts as 10 for skill checks you're proficient in), the Eloquence Bard has 'Silver Tongue' (similar but only for Persuasion and Deception checks using charisma). I don't think any feats grant this, but I'd consider it valid if it was 'always on'. Glibness, the 8th level spell wouldn't count as it's not an 'active all the time ability' and I'm only interested in things you can have active all the time.
Are there any other similar abilities granted as class/subclass abilities or feats, and if so what are they?
I'm narratively trying to find a way that a character might always be reliable at some skill, without being super-human at it.
