Larian Studios Forums Baldur's Gate III Baldur's Gate III - Suggestions & Feedback Damage calculations

Im having a hard time figuring out damage calculations, it feels as if stat modifiers are not figured in properly.
If I have a 16 str, then minimum damage with a long sword should be 4 (because it would deal 1d8+3), and if I shoot something with a bow while having a dex of 16 the same should apply. Yet I seem to hit for lower damage than the dice suggest I should, am I missing something?

Deppends, is this at the begining of the game against a Imp? Imp's have a special feature they have fire immunity and resistance to all physical damage types, meaning they take about half the damage they were supposed to take. So they can take as little as half your minimum and a max damage of half your maximum.
