* a character with only a single class, with this BAB progression, gains an additional attack at this point.
This Table is based on the Class Level, not the Character or Race Level.
CALCULATION: # of attacks = ( +BAB/5 ) Rounded up.
==Multi-Class Progression==
When a character multiclasses each class, the BAB progression is based on the class level. Each class provides separate BAB progressions, even if the BAB each class provides is of the same type the progressions do not follow on.
e.g.
a level 20 Rogue (a medium BAB) has a +15 BAB, while a character with 10 Rogue levels and 10 Monk (also a medium BAB) levels would gain +7 BAB from each class, for a total of +14 BAB at Character Level 20.
Another example could be a character that (for some reason) had 1 level each of warlock, rogue, bard, and monk - all classes with medium BAB progression. Such a character would have a total of + 0 BAB at Level 4 of that Character/Race. It is advantageous to stop advancing in a class just before there would be a pause in the BAB progress. Medium BAB progression classes gain no BAB increase at first level and every 4th level thereafter (levels 5, 9, 13, etc.) thus a Rogue (8) / Warlock (8) / Bard (4) would have the same +15 BAB as level 20 Rogue.
