Base Attack Bonus Progression

Base attack bonus relates to a character’s ability to fight both in melee and ranged combat. There are four varieties of base attack bonuses now: Outstanding, Good, Average, and Poor. When you take levels with the same base attack bonus (regardless of class), you stack your classes for determining the bonus you get. If you multiclass into two classes with different progressions, you count each one separately and then add the two numbers determined from the chart.
