I've seen fractional BAB mentioned several times in threads regarding multiclassing, but I've never seen it explained. I was wondering if anybody could explain this (presumably simple) process to me, or show me where to find a description/explanation of it.
Thanks.
It's from Unearthed Arcana. Give me a minute and I'll see if I can find it on the SRD.
EDIT: I must be looking in the wrong place, because I can't find it on the SRD. It's on pg. 73 of Unearthed Arcana, though. Basically, it means that multiclass characters don't have crazy high saves and stupidly low BAB. For example, without fractional BAB/saves, a Wizard 1 / Sorcerer 1 (don't ask why you'd take that class combo) would have BAB 0 and Will +4. With them, the same character would have BAB 1 (form having 2 levels in BAB 1/2 classes: 1/2 + 1/2 = 1) and Will 3 (the same as you normally would from having 2 levels in a class with good Will). You only get the +2 from having good saves once, but you add all the fractional pieces of your BAB and your saves together to get a much more reasonable whole.
Each class progresses your BAB by a certain fraction; .5 for classes like Wizard, .75 for ones like Rogue, and 1.0 for ones like Fighter. At each level, add that number to your BAB total, and for the purposes of attack round down to the next whole number.
For example, a Cleric 3 Wizard 2 Fighter 3 would have 2.25 + 1 + 3 = 6.25 BAB.
While correct, this is not the best example, because BAB 6 is what a cleric 3, wizard 2, fighter 3 would have already.Quote:

Cleric 2/Rogue 2/Druid 2/Bard 2 would normally have a BAB of +4. Under fractional rules, it's +6.
Excellent, thank you all.
Looking at this example, I'm assuming the Saves are fractional as well?Quote:

Yes. Getting the +2 only once in each save isn't part of the fractional rules, though; the sample character in UA gets the +2 Fort from both Cleric and Fighter levels.Quote:

The sidebars didn't make it.Quote:

Obviously, it makes no sense to get the +2 twice per save since that means multiclassed characters get better saves than singleclassed characters with full good progression. That's just dumb, but default UA printing says nothing against it. Luckily, it's easy enough to implement on your own.Quote:

For example, a Rogue has 3/4 BAB. Wizard has 1/2 BAB.
Under core rules, a Rogue 1/Wizard 1 has +0 BAB, as both have only +0 BAB at level 1.
Using fractional BAB, a Rogue1/Wizard 1 has .75+.5 or 1.25 BAB, which rounds down to +1.
You're right, that's an incredibly stupid way to make it work. I mean, it's how it works without fractional, but really, who uses non-fractional calculation? :smalltongue:Quote:

Note that late WotC printings have prestige classes that do not penalise 3/4 BBA (Ordained Champion comes after cleric 4, while older PrC need 5 levels at least, wich is bad for clerics and especially rogues (we're looking at you, assassin)). So fractionnal BBA isn't really how the game was intended.
The only times I wanted that rules was when I was building early entry Arcane Hierophant and early entry Arcane Trickster.
Edit : the saves matter to Master of Shrouds and Thrall of Juiblex. All hail lv4 PrC entry !
I use fractional BaB but not fractional saves.
So what sorts of saves does that leave a Necropolitan Dread Necromancer 4/Cleric of Undeath 3/True Necromancer 3/Pale Master 10 with?Quote:
