But if you roll under the halfway mark, it's considered a good success, and if you roll under the quarter mark it's an amazing success. So if your skill's score is 12, 1-3 is amazing, 4-6 is good, 7-12 is a plain success, 13-19 is a failure, 20 is a crit fail. You roll both the main d20 and a situation die, either as a bonus or penalty, chosen by the DM, so an easy task might have a d6 rolled and removed from your d20, a hard task might add a d10 to it, because rolling low is good.
Is there remotely any ways to automate that math, or would that need a dedicated ruleset to pull off?
