No rule is inviolate
Ah, that makes sense.Not in 5e proper, but I did use it during the playtest. The thing is, the problem that crit confirmation was designed to solve doesn’t really exist in 5e thanks to bounded accuracy....
By the math, it appears it's (relatively) easier to confirm 5E hits than 3E due to bounded accuracy and armor class caps. That could be a problem.
For those who don't know the cards, here's an example. Rules: roll a Natural 20, then "confirm" the hit to draw a card. Otherwise, normal damage (or at our table, max damage on the weapon die regardless). They were meant to make Critical moments more dramatic and varied.
