Base Attack Bonus

The Base Attack Bonus (BAB) is always equal to your character level.

For example, a Level 2 Scoundrel has a BAB of +2.
A level 3 Scoundrel/level 4 Noble has a BAB of +7.

Reasons for the House Rule:
1) Defenses raise one point for every character level, the same for every class.
2) Favouring multi-classing.
