Most attacks per round

[Shazman]

A fighter 6/dervish 10 with all of the two-weapon fighting feats plus boots of speed can also get 15 attacks a round.

But not by using the Core rules.

If we open this up beyond the OP's request of core only we'll see all sorts of wackiness. For instance, your dervish could add 4 levels of Thrall of Demogorgon for an extra full round action once per day.

In that case, a 16th level ranger with the twfing melee combat style with boots of speed would have 8 attacks a round.

Once you start using monsters and templates from the monster manual, you might as well go for non-core stuff. Using non-core material, I can give that same dervish the snap kick feat (Bo9S) for a total of 16 or 17 attacks a round.

And still not have more than the monk.

Note that when I say "the monk" I'm refering to a build that actually has at least one level of a class with a fighter BAB so he can get a +16 base attack some time before epic levels. It really only needs 11 levels of monk for the two attack flurry. I've also been ignoring haste for the most part, since it's something that every single build answering this question should have in one form or another.

I'll have to diagree on this one. If the question is "what core ___?" and the answer contains nothing but material from the core rulebooks, it's hardly an open invitation to use non-core material.

A 12 headed hydra has 12 bites. Greater Two Weapon Fighting + Rapid Shot + Flurry of Blows only gives 11, but you get to keep all your class abilities and can do it in a small area where being huge is annoying. You can also take all those attacks at range if need be.

A fighter 4 / monk 16 has BAB 16. I think it would get one extra iterative attack than a monk 20 without losing out on any of the other attacks.

 

[Shazman]

Am I missing something here? Minus haste, wouldn't the fighter/monk have 6 attacks a round (4 for 16 or higher BAB + 2 for flurry), while a fighter or ranger with greater two-weapon fighting would have 7 attacks a round (4 for 16 or higher BAB + 1 a piece for the three two-weapon fighting feats). This also doesn't account for non PHB races or templates from the monster manual. Now, if there is some bizzare ruling that lets flurry stack with two-weapon fighting, you can easily get 9 attacks without haste or crazy centaur half-dragons (which wouldn't work as well because they would lose about 5 points of BAB due to a massive level adjustment which seems to be completely ignored in your build).

Did I not include that in my 11? 4 BAB + 4 GTWF + 1 RS + 2 Flurry = 11. Adding half-dragon centaur gives 2 hooves and a bite for 14. Haste gives another one for 15.

Snatching the juggler idea for 6 dancing weapons adds a whole bunch more. Is there a clarification somewhere for Dancing? The SRD says it uses your BAB, which seems to indicate that it doesn't get your ability modifier, feats, or class abilities. But that makes an otherwise decent weapon enhancement way too expensive at +4. Even at 20th level you've got at most a +20 to hit, which is going to miss a lot of the time. And the iterative attacks are even worse.

Ah, I guess you did. I saw "hasted TWF monk" and thought you meant single classed.

 

[James McMurray]

No prob. I explained more fully later on, but at first was vague about what I meant.

Monk 16/Fighter 4 with Two-Weapon Fighting feat Poly'd into a dire tiger. Charge, pounce. Flurry of blows, then all natural weapons (treated as secondary natural weapons, per FAQ). And don't forget the rake.

Add a Haste attack, if you DM allows it. (Most do.)
