I couldnt find in the forums so sorry if it was asked before

Question is simple. How do you calculate Bow damage in BG1:EE? I know that Strength bonus is added to slings but what is the case for bows? I am asking this because Minsc is doing some serious damage with his bow.

Here is the summery of the situation:

Minsc,
Strenght 18/93,
Dexterity 18 (because of gaunlets of Dexterity)
Bow: Composite Longbow. (+2 Dmg, +1 Hit)
Normal arrows. (D6 = 1-6 dmg)

On the right side it shows D6+2 = 3-8 Dmg.

So doesnt that mean it gives maximum 8 damage to the enemy? But Minsc did 12 Missle damage to the gnolls in the Gnoll Stronghold with a roll of 14. Where did that extra 4 damage come from?

I hope i was able to explain my question
Tnx.
Engin.

EDIT: Added roll information.

Sounds suspiciously like a critical hit to me.

The roll was 14. I forgot to add that in the description. In a critical he hit 18

As well as the racial enemy bonus, bows are set to two attacks per round.

The racial bonus would account for it, but the second attack would yield a separate attack roll and damage roll.

Thank you. This looks like the reason of extra +4 Dmg.
