I would love to bump the thread and bring something to Larian attention since this "feature" still in the game and in some other places people were speculating that criticals on skill checks got in the game because of OneD&D in the first place.
So, Larian, please notice that in current issues of OneD&D the rule was changed again and "criticals" were removed from skill checks and replaced with granted Inspiration. That's because it also got negative response from play-testers. You may presume by now that no one loves the thing to be used as an actual rule.
First issue of OneD&D:
D20 TEST
The term d20 Test encompasses the three main d20 rolls of the game: ability checks, attack rolls, and saving throws. If something in the game affects d20 Tests, it affects all three of those rolls.
The DM determines whether a d20 Test is warranted in any given circumstance. To be warranted, a d20 Test must have a target number no less than 5 and no greater than 30.
ROLLING A 1
If you roll a 1 on the d20, the d20 Test automatically fails, regardless of any modifiers to the roll.
ROLLING A 20
If you roll a 20 on the d20, the d20 Test automatically succeeds, regardless of any modifiers to the roll. A player character also gains Inspiration when rolling the 20, thanks to the remarkable success.
Rolling a 20 doesn’t bypass limitations on the test, such as range and line of sight. The 20 bypasses only bonuses and penalties to the roll.
Current issue of OneD&D:
D20 TESTS
The term d20 Test encompasses the three main d20 rolls of the game: Ability Checks, Attack Rolls, and Saving Throws. If something in the game affects d20 Tests, it affects all three of these rolls.
Whenever a player character rolls a 1 for a d20 Test, that character gains Heroic Inspiration. The DM determines whether a d20 Test is warranted in any given circumstance.
