Some features, like the Fighter Champion subclass 'Improved Critical' ability, allow a critical hit on rolls less than 20 (the aforementioned Improved Critical allows crits on 19-20, for instance). Is there any way to make Beyond 20 automatically do that? I thought maybe the Custom Critical limit, but I wasn't sure what that actually does.

Do you mean Beyond20 or D&D Beyond? Or do you mean Roll20?

Beyond20 is the extension (not associated to D&D Beyond officially by any means).

Beyond20 and D&D Beyond do automatically do it. Well, D&D Beyond automatically does it and that feeds into Beyond 20.

Not 100% sure about Roll20, however.

Above is a Natural 20 - below Natural 19 (Crit) because of Champion Improved Critical

 EDIT: Or are you asking, aside from being a Champion?

I can't recall all the FEATS, but I do not believe there is one that is similar to Improved Critical which Champions get.

But you could, with your DM's approval, homebrew it probably.

I was referring to when you make a roll in D&D Beyond (and it carries over through Beyond 20), was there a way to make it account for the increased chance of a crit, such as a Champion's Improved Critical ability? Because my experience was that it did NOT. I distinctly rolled a natural 19 on an attack with my 3rd-level Fighter Champion, and it did NOT treat it as a critical hit. It may or may not be worth noting that said roll was with a Unarmed Strike (and the Unarmed Fighting Style) and not technically a "weapon".

RAW, unarmed does not trigger the crit on a roll of 19

Beginning when you choose this archetype at 3rd level, your weapon attacks score a critical hit on a roll of 19 or 20

but talk to your DM for their ruling on it.

if it’s a weapon attack, dndB and B20 will both output correctly

 As Stavros_Araatan pointed out - if it was unarmed, this is probably why as it requires a weapon.

As you can see in the second post - I rolled... a lot of times... until I got that 19. And it rolled in D&D Beyond as a Critical and did all the extra dice, which it then shoved through Beyond20, as expected.

 Well then that explains it. But IMO it seems to be an unnecessary distinction and is parsing out the language a bit too precisely, especially for a Fighter who has actually taken the Unarmed Fighting Style.

 Yeah - there's a few times where punching someone and using a skill or whatever is not RAW, but I've allowed it. I had a Paladin who wanted to punch a monster and expend smite - which technically requires a weapon - but I allowed it. Because it creates this cool visual that their fist is this holy energy in a moment of fury.
