To what extent is multiclassing frowned on? Or is it only with classes that have very specific RP responsibilities that it is frowned upon?

Basically what here is acceptable/isn't and for what reasons

Fighter (4) Cleric (1-whatever) Fighter (4) Monk (1-whatever) Fighter (1) Rogue (1-whatever) Rogue (1) Monk (1-whatever) Rogue (x) Monk (x) Paladin (1) Sorceror (1-whatever) Rogue (2) Fighter (1) Wizard (1-whatever) Monk (6) Rogue (x) Shadowdancer (1)

Etcetera, I need some guidelines. :)

Many of the more heinous multiclasses are restricted by canon. So, you're not going to see paladin/rogue/sorcerers, but you might see a paladin/sorcerer of Mystra. The general rule is that it has to make IC sense. Even if there's no rules against blatent powerbuilds, I frown upon them, and certainly the PC will not be getting any perks from me. An example would be barbarian/fighter.

Multi-classing is frowned on when it doesn't make sense, and no explanation other than mechanical advantages are given.

I don't think anyone can give you a "go/no go" formula for that laundry list of multi-class recipes. I surely can not!

I personally find many monk/whatever and paladin/whatever permutations cheesy. Some could be great though.

Doesn't multiclassing Monk with a Full BAB progression class give it higher AB than it should?

I don't think so. I think it can glitch to give additional attacks when dual wielding monk weapons however. (Kamas)

The class combination I have in mind right now is either: rogue/fighter/bard, or fighter/bard. The concept is an all-out adventurer whose specialty is having no direct specialty, but instead is simply very able to encompass the large range of abilities that are called upon for an adventurer to succeed. That said, I wouldn't be going 2 rogue (for evasion)/4 fighter (for specialization). It would be 1 rogue/1 fighter and then bard after that.

I'd like to hear what the DMs think on this build concept in specific from what you've read here. Thanks for the responses. :)

Edit: I remember what it is about fighter/monks. A fighter/weapon master/monk using kamas can essentially take 1 monk level (although would probably take 6 for powerbuilding purposes, and we're talking with at least level 20 in mind for an end level) and have the bab attack progression go: +20/17/14/11, for instance, instead of +20/15/10 which it would as a normal fighter/weapon master.

fighter/bard/rogue seems most excellent to me, sir. Yet remember that it's about RP before build.

Just make sure any multiclassing you embark on has a sound reasoning and is consistently RP'd to the best of your ability, and you'll be fine.

The only two builds I'd ever generally ask a player about are:

1.) Druid/Monk. 2.) Cleric/Monk.

We have a few players here who could likely justify these builds, and really there is no problem as long as the character history makes sense.

<3 Me love you long long tiem.
