Attack Roll

An attack roll is a roll to determine whether an attack hits.
To make an attack roll, roll 1d20 and add the appropriate modifiers for the attack type, as follows:
*Melee attack roll = 1d20 + base attack bonus + strength modifier + size modifier
*Melee attack roll (with Weapon Finesse feat) = 1d20 + base attack bonus + dexterity modifier + size modifier
*Ranged attack roll = 1d20 + base attack bonus + dexterity modifier + size modifier
*Ranged attack roll (with Zen Archery feat) = 1d20 + base attack bonus + wisdom modifier + size modifier
In either case, the attack hits if the result is at least as high as the target's armor class. 
==Automatic hits and misses==
Rolling a natural 20 results in an automatic hit; rolling a natural 1 results in an automatic miss.
