Attack Roll
An attack roll represents your attempt to hit your opponent in melee or from range on your turn in a round. When you make an attack roll, you roll a d20 and add your attack bonus (see Ranged Attacks and Melee Attacks below, as well as the Basic Attack and Damage Bonuses sidebar on page 241). Various other bonuses can apply from class features, feats, and so on. If your result equals or exceeds the target’s Armor Class, you hit and deal damage.

When making a ranged attack, you use a ranged weapon to shoot at an opponent from a distance. If you’re attacking with a thrown weapon, your ranged attack bonus equals your base attack bonus (determined by your class and level; see Chapter 4) + your Strength modifier. Otherwise, your attack bonus for a ranged attack equals your base attack bonus + your Dexterity modifier. When you make a ranged attack, you might also take a penalty for shooting or throwing your weapon beyond the distance listed as its optimal range (see Range and Penalties on page 245).

When making a melee attack, you use a melee weapon to strike an opponent in hand-to-hand combat. Your attack bonus for a melee attack is equal to your base attack bonus (determined by your class and level; see Chapter 4) + your Strength modifier. Source Core Rulebook pg. 240 |
A natural 1 (the d20 comes up 1) on an attack roll is always a miss. A natural 20 (the d20 comes up 20) is always a hit. A natural 20 is also a possible critical hit, which could deal more damage (see Critical Hits on page 245). Source Core Rulebook pg. 240 |
