[*] Dice rolls: these should have the bonus/penalty modifier added to the value of the dice rather than subtracted to the target. Apparently this is not just a subjective matter but contradicts the D&D rules that rolling a 1 is an automatic fail no matter what.
[*] Guaranteed skill-checks: If there's literally zero chance to fail, I shouldn't need to roll.
Hello there, i dont know if that was already mentioned. But rolling a 1 on skill checks does NOT result in automatic failures. Here is the PHB reference quote:
Quote
To make an ability check, roll a d20 and add the relevant ability modifier. As with other d20 rolls, apply bonuses and penalties, and compare the total to the DC. If the total equals or exceeds the DC, the ability check is a success — the creature overcomes the challenge at hand. Otherwise, it’s a failure, which means the character or monster makes no progress toward the objective or makes progress combined with a setback determined by the DM.
in the whole text for ability checks it is not mentioned that 1 is an automatic failure or 20 a automatic success. An Ability Check can fail on a 20 if the total exceeds the DC required and the same for rolling a 1, it can succeed if the total is equal or more of the DC required.
