Larian Studios Forums Baldur's Gate III Baldur's Gate III - Suggestions & Feedback Rolls and situational advantage/disadvantage

There is an established system of how to translate DC difficulty and you are, respectfully, way off:

DC 5 = very easy
DC 10 = easy
DC 15 = medium
DC 20 = hard
DC 25 = very hard
DC 30 = nearly impossible

Keep in mind you have ability modifiers and proficiency bonuses, and in early access characters are very low level. Things like expertise eventually come into play. I do think Larian could do a better job implementing systems like using help to gain advantage on a check (when it makes sense), the guidance cantrip, etc. although some of this will be trickier in a video game setting.

It's also easy to miss but the "target" system they are using is not the same as the DC. If the DC is 15 and your character has a +5 to the check (2 from proficiency, 3 from ability mod) then the UI will show a target roll of 10. So that character with +5 has a 55% chance to succeed on the roll. There are a lot of complaints that this is a weird and confusing way to do it.
