Nat 20 and Nat 1 are called out. With a DC set, you get a pass/fail verdict.
Four Fate dice (+ / blank / −) plus your skill. Ladder result is named, from Legendary (+8) down to Abysmal (−2).
Both dice ace (explode). Best result vs TN 4 — every 4 over is a raise. Two natural 1s is a critical failure.
Chronicles of Darkness: d10s, 8+ is a success, "again" dice reroll and add. 5+ successes is exceptional; 0 successes on a chance die means dramatic failure.
5s and 6s are hits. Half or more 1s is a glitch — with zero hits, a critical glitch.
Call of Cthulhu 7e: roll under skill. Extreme = fifth, Hard = half. Bonus/penalty dice swap the tens die. 96–100 fumbles at low skill.
