I'm a total Pathfinder newb and I have a question that will probably reveal just how "newb" I am.
According to the Core Rulebook, to calculate an attack roll, you use the following formula:
d20 + attack bonus
For melee attacks, your attack bonus is calculated as follows:
Base attack bonus + strength modifier + size modifier
With this in mind, consider the humble goblin, found here:
Let's say the GM is going to make a melee attack roll for this creature, versus a PC. Does he add +1 for the small size, another +1 because of its Base Attack Bonus, plus the strength modifier (0, in this case) and then add the +2 listed for the short sword melee attack?
Or does he simply add the +2 for the short sword melee attack, as if all the other factors were rolled into this number?
