Alternative Base Attack Bonus


Homebrew and House Rules


I was always bothered with the way d20 tied BaB with level. Why should the lvl20 Expert librarian old man that never touched a blade have a BaB comparable to a heroic lvl15 Fighter? He shouldn't be lvl20 you say, since he never fought anything tougher than boredom and bookworms. Then how would he have the +25 to Knowledge (history) so fit for his role? "Just give him what's needed and don't bother" you might say. Well, I prefer a systematic approach, and since I found one that works fine for me, here it is:

Instead of a BaB bonus, at each level a character can gain a number of extra skill points as follows:

+3 for a fast BaB progression.
+2 for a medium BaB progression.
+1 for a slow BaB progression.

Thus, a lvl20 expert can have +2 maxed skills and 0 BaB, a caster character can choose to give up physical combat potential and a score of aimed spells for additional skill options and basically a multitude of non-combat NPCs can receive far more representative stats with a very simple rule that as far as I understand, doesn't break anything at all. What do you think?

EDIT: Of course, this requires tracking decimals of BaB. So for example, a lvl1 wizard has a 0.5 BaB and a lvl1 cleric gets 0.75. As normal, only the integral part counts for all intents and purposes other than tracking.

Not a good idea to screw with the internal math of the game without carefully figuring out how it will affect things.

Also, your example isn't accurate. No body gets to 20th level by hanging out in a library all their life. Unless they're a 1000 years old. In that case, they probably could take on a twenty-something-year-old fighter. I'm not reeally understanding your logic here.


My line of thought begins in the interest of producing representative character stats for non-combat characters, while still providing access to high skill ranks.

A very talented armorsmith, a highly dedicated scholar, a diplomatic aide or a miracle working archbishop are all viable character concepts that by the rules face a simple dillema: making them high level characters means that they are by necessity far better combatants than a level 1 fighter, even though it is highly probable that they never carried, let alone swinged, a weapon. On the other hand, making them low level characters denies them access to high skill ranks which is the essential component of their roles.

This can have two possible solutions:
1) Make those characters high level ones, finding an alternative to the correspondingly high BaB, which is the solution I suggest, or
2) Make those characters low level ones, providing an arbitrary bonus to the skills of interest. This being the simplest solution and the one I run for many years, has the main problem of being awkward when applied to non-combat PCs.

EDIT: An additional problem arises with clerics, where archetypes involving the scolarly kind of cleric, like the above mentioned arch bishop, must be able to cast high level spells yet they should have little in the way of combat capacity.


Seems problematic. I would advise against tracking fractions, and let them trade 1 point of base attack bonus for a set number of skill points, say 3. It's a poor trade in my opinion and I don't see why anyone would want to.
With the scaling nature of opposition every point of BAB is precious.
A free feat would be a better trade. Still likely not worth it.
Ninja'd : I see it's for NPCs, no worries then.About the trade value and needing to be able to hit things.

It's not about presenting an equal trade but merely providing an option to represent characters that although worthy of being considered high level, at least skill wise, nonetheless should not actually pose as considerable combat challenges. A number of examples occur at my second post.


I understand. I still advise just making it a set value trade. 1 BAB for 3 skill points or a feat. That way there's less to worry about in terms of differing values for differing BAB progressions.

It sounds like you don't understand how the math of the game works.

Essentially it's the same thing, but phrasing it 1 BAB for 3 skill points means for example that the wizard gets those skill points every second level. Also, I realize that the relation between the three BAB progressions is 0.50, 0.75 and 1.00 which is not represented by 1, 2 and 3 skill points properly, instead requring 2, 3 and 4 (1 for each 0.25 gained). In practice though, a class with a fast progression should never give up its BAB, except possibly in the case of a fighter becoming a commander that keeps out of actual combat as his career progresses, or similar concepts.

I would not take the Feat option, this would provide very early access to prestige classes thus escaping the purpose of this house rule which is to provide a solution for high level non combatant characters.

The game designer behind 3rd Edition deliberately built the math with the assumption that the greatest humans of real life would be roughly 5th level characters. Anything above that is superhuman by our standards. Justin Alexander explains it in this article (see Crafting and Knowledge). A great blacksmith that spent all his life as a smithy would not be a 20th level character. As shown by Alexander's math, Albert Einstein would be a 5th level expert, making his BAB only one higher than a fighter.

Your proposal also largely ignores many other important factors that contribute to a character's power, such as ability scores, feats, and wealth. A non-combat character will spend their feats on things like Skill Focus. You ignore the numerous ways a non-combat character can increase their preferred skill, such as having masterwork tools and assistants. You don't need to give them arbitrary bonuses.

Finally, this is a combat game. If someone makes a purely non-combat character, they will likely not be as effective as other characters. Even so, the game doesn't stop them from being really good at non-combat stuff.


A few things:
1- You don't need a 20 level expert to get a +25 Knowledge bonus. A 10 level one with Knowledge(history) as a class skill, the feats Skill Focus Knowledge(history) and Scholar: Knowledge(history) and some other Knowledge, and an int of 14 has +25 Knowlegde History bonus. Higher if he puts more points in int. So you started from a flawed proposition.
2- If, somehow, you get an expert to twenty level without a single fight in his life (practically impossible with the way experience works), he probalby has read enough health and fitness books and martial arts manuals that he can wipe out most tenth level fighters. a 20th level anything is a demi-god and the demi-god of historians being able to beat the barely superhuman fighter is something that should be able to happen.
3- You're not accounting for the combat feats and class abilities the fighter has. Like a +3 from weapon training or a probable weapon focus feat, and also the fighter will have a much higher strenght score since PCs have way more points to buy attributes than NPCs. A fifteen level fighter will have a much higher BAB than a 20 level expert. You cannot claim to be sistematic while ignoring huge swats of the system.
4- Why in the name of Nethys would you need a +25 bonus to knowledge? The highest DC you can get on a Knowledge(history) check is 30, and that is for something absurdly ancient and obscure like the name of a minor azlantean noble from before the starstone fell. You can reach that with a +20 bonus and taking 10.


A half elf of any class that has Know(history) as a class skill can have a +X to it at level 1.

Skill focus adds 3 + class skill adds 3 + 5 from a high int + 1 rank + the feat Master of Knowledge (weird requirement for deity but lets ignore that) will allow you to reliably achieve a 22 know(history) check by taking 10. Once per day, this person can treat their know(history) roll as if they'd rolled a natural 20, giving them a 32 skill check.

As stated, a DC 30 is pretty much the hardest check you could make. And our level 1 PC can do that once per day.

Thanks for all responses!

EDIT: Thinking about what led me to have such a distorted view, somewhat shameful, considering I've been storytelling in d20 for the past 15 years, I understand that a big part of it were the demographics rules of cumminity generation in 3rd. They were quite clear on having a couple 8-10 level characters in almost every notable city, rather than them being a one of a generation occurence, along with a host of all levels between 1 and max. The Forgotten Realms campaign setting provided a similar view, if not even more extreme.

The article you cite is a good exercise, and an interesting perspective. It is also an opinion whose supporting evidence is based almost entirely on hit points, and how many average 1st level Orcsiz Aragorn can kill. (EDIT: This is a deliberate exaggeration. I find much of the number crunching "evidence" in his article skewed in supporting a predetermined outcome.)

"The game designer" behind 3rd Edition did NO such thing.

3rd Edition DMG, page 36 under NPC classes, "The fact that each NPC class has differing levels provides the DM with a means to measure NPCs against each other. A typical blacksmith might only be a 3rd-level commoner, but the world's greatest blacksmith is probably a 20th -level expert. The 20-level blacksmith is a capable person with great skill, but she can't fight as well as a fighter equal to her level (or even one much lower in level), nor can she cast spells or do the other things that characters with PC classes can do."

Now it goes on to say that most NPCs don't rise to more than 3rd level, and I am not suggesting that 20th-level experts are common...or rare...or even make sense. But the classes were provided as tools for GM's to make the NPCs they want and need.

Also, the 3.x DMGs have demographics tables, missing in PF, that generate "naturally occurring" commoners of up to 20th-level. In fact, the average "highest level commoner" in a thorp, is 7th! In a metropolis, the average "highest level commoner" is 20th (higher than 20 is reduced to 20).

While what you are stating is true mechanics-wise, it is pretty extreme. In D&D, it used to be considered that the IQ of a character would be ten times his intelligence score; so you are talking about a character with a 200 to 210 IQ putting him in a very small group of the most intelligent people in the world, well above the Stephen Hawkings and Einsteins of our little world.

Take that score down to 14 where he is only very intelligent (but more believable) and your calculations change quite a bit from a 32 skill check to 19. Still good, but not outrageous.

'High level' non-adventurers is one place where game mechanics fall short and GMs would need to step in and place limitations for the purpose of balance.

After all, a person who has worked all their life as a cabinet maker and eventually becomes a highly skilled master craftsman may not know a lick about swinging a sword around...and let's not even talk about hit points.


All in all, I think that while the position of the article is certainly not the same as the designers of d20, it is practical enough to account for most, if not all, needs. The only example I think that fails that position is the scholarly priest archetype, that needs to cast high level spells without being a combat powerhouse, which is covered (considerably less elegantly) in the follow-up article.

Don't get me wrong, if you agree with that article, and it brings value to your GMing, then more power to you. I'm just tired of the claims of the absolute fact that "normal" stops at 5th level.

Be careful with your words because "D20" is a game system, but d20 is also the name for any RPG that uses a twenty-sided die. They're not necessarily the same. Neither Pathfinder nor D&D 3.5e belongs to the D20 System.

The high level clerics and wizards in cities are typically retired adventurers. It's difficult to challenge and strengthen one's faith by sitting in the comfort of a church all day, reading scripture. Even great prophets of real-world religions that healed and performed resurrections traveled the world and went on adventures. Also keep in mind that most of a church's clergy in Pathfinder are actually commoners, experts, or low level clerics. Most servants of a god don't cast spells. Only a select few do and they are either very old or have seen action.

No matter how you look at it, you're not going to find a character who got 9 cleric levels by spending their whole life doing priestly duties in a church. That's not a flaw. This is a game that reinforces a world where triumphing over adversity makes you stronger.

It makes sense if you consider that in a magic rich environment more people are born above average and that in a high adventure world there are more chances and paths for talented people to rise above others and become better.

If you compare NPC arrays with point buy and Arrays for PCs and important NPCs you'll notice that in universe these are people who are simply naturally born with higher attributes.

A person who has worked all their life as a cabinet maker and eventually becomes a highly skilled master is still a 5th level character. You need 2,400,000 experience points to reach level 20 on the fast track. There are no rules for getting experience from working or even training. Even if the expert cabinet maker gains points for defeating social and skill encounters, if he lives a mundane life he will NEVER find an encounter that gives him the 5,000 thousand xp needed for sixth level much less the 2.4 MILLIONs needed for twenty levels. With normal CR1 and CR1/2 encounters, which would only hapen once on twice a month (a cutpurse trying o get his cp, a hardy bargaining noble) he would take thousands of years to reach high level.

That there is another reason that can explain why the best of our world is level six once a generation but Golarion has hundreds of them in every city. We just don't have high CR challenges to give enough XP in one lifetime to break that barrier. It took the Theory of Relativity encounter to get Albert Einstein to sixth level. It took most of WW2 to make badass like Simo Hayha and Audie Murphy.

D20 is not a stand alone game system, it is the unified underlying framework of several game systems. Chief among these is most definitely 3.0 and 3.5 D&D, as this was where "the designers" codified d20. Plus there's the D20 System logo on the cover. The reason Pathfinder is not a "d20 System" product is because it requires WotC's permission to fly that flag.

For what it's worth I agree with you. In a fantasy setting where warriors and mages gain abilities that far outstrip those of real world humans, the bookworm/researcher equivalent should also exist. An entire campaign taking adventurers to level 20 could take place in much less than one year. So, an elf that lives to be 500 can't have spent that entire time researching enough (non-combat encounters) to reach level 20? If he does, should this mean that he has more hit points and weapon skill than a low level warrior?

My solution to this was to use the NPC classes but limit their hit dice as they progress. An expert only gains 1 HD for every 5 levels they possess, for example. That way you are keeping the maths of the skill system and just slowing the progression of the combat baggage.

It's still a game system. The last sentence there is why I brought this up in the first place
