As usual, I tagged this for 2024, but it applies equally to 2014 and presumably to your 5e-alike of choice, as long as it has advantage and disadvantage.
Much digital ink (should that be many pixels…?) has been spilled on the problems with advantage/disadvantage stacking. While advantage and disadvantage is in many ways an elegant fix to the endless parade of + or - 1 or 2 modifiers of 3e and 4e, but to many, it felt like a slight overcorrection.

Well, I think I’ve come up with a solution, and credit where credit is due: I’m stealing the idea almost directly from Brennan Lee Mulligan (so Dimension 20 fans, apologies in advance if this idea is old news to you). Brennan has used this mechanic on only a few occasions so far in Critical Role and hasn’t called it by a specific name there, but I’m given to understand that in some of his other campaigns, he has used this mechanic and called it “rolling with emphasis.” The idea is, similar to how a d20 test can have advantage or disadvantage, it can also have emphasis; when you make a d20 test with emphasis, you roll twice and instead of taking the higher or lower result, you take the result that is farthest from 10.
