How to Attack

To roll "to hit," the attacker rolls 1d20 and adds their attack bonus (AB), as shown on the Attack Bonus table, as well as Strength bonus (if performing a melee attack) or Dexterity bonus (if performing a missile attack) and any other adjustments required by the situation. If the total is equal to or greater than the opponent's Armor Class, the attack hits and damage is rolled. A natural "1" on the die roll is always a failure. A natural "20" is always a hit, if the opponent can be hit at all (for example, monsters that can only be hit by silver or magic weapons cannot be hit by normal weapons, so a natural "20" with a normal weapon will not hit such a monster).
