New Rogue Two-Weapon Fighter Ideas

[Lopke_Quasath]

Go Human for the extra feat, skill points, and the Human Paragon levels, since you said you liked it.
As a starting point go Rogue 1st level. Get Weapon Finesse (1st), TWF (1st). Put ranks in Bluff. 2nd level go Fighter 1 and take Combat Expertise. Improved Feint next.
With a 32 point buy, maybe go: Str 12, Dex 17, Con 12 (or 14 if your Wis is 8), Int 13, Wis 10 (or 8 if you want Con 14), Cha 12. At 4th level go Dex 18.

Use a rapier and a kukri in your off-hand, for the high crit ratio. Keep a spare short sword when fighting things immune to crits.
Use a few BAB to boost your AC while using Weapon Finesse to still have a decent chance to hit.

I played a halfling TWF fighter/rogue with 2 kukris. He was a lot of fun to play. Enjoy your own TWF rogue!

Cheers

The Telling Blow feat from PHB II is nice for rogues with a weapon with a wide critical range, it's a nice feat that allows the addition of sneak attack dice on critical hits.

As cliche as it appears, the famous TWF with paired scimitars give you the d6 goodness with the 18-20 crit potential.

Paired Sai are excellent so long as your character is Medium-sized and you are fighting humanoid opponents with weapons. Lots of disarm attempts at the cost of damage output.

If psionics are allowed, consider playing a Soulknife.

You really want to freak the DM out, ask to play a Gnoll Ranger/Rogue. I am IMC and he's all sorts of chewy fun.

Consider taking a couple of levels of Paladin - Ftr2 / Rog4 / Pal 3 - and then take the Divine Crusader PrC with the Instinct domain.

Paired scimitars would give you higher penalties (-4, -4) since they are not light weapons.
Go rapier and kukri for the crit factor.

Unless you go Dervish PrC, then you could use scimitars as light weapons. Which is a thought, but would need more of a fighter angle than a rogue. And also probably doesn't work with an urban/dungeon theme (Dervish being a tribal warrior concept).

For the Divine Crusader PrC you would need a Deity that matches your alignment and has the Instinct Domain, plus you would need Weapon Focus in the deities favored weapon. Pretty specific requirements. What are the deities in Ptolus like?

I played a halfling two weapon fighting rogue up to 9th level before he died and I found it difficult to make use of both weapons effectively. Basically you are relying on your party members to make the movement to enable you to get into a flanking position and as you say a number of them are inexperienced I think you may find this difficult. For example, it works better for you if your barbarian moves into the side of an opponent and therefore you can then take up the other side - if the barbarian simply moves or charges into the front you somehow have to get around the back, which often leaves you alone in the thick of things. In fact the best way to get a flanking full attack is to encourage the opponent to charge you, then delay until your barbarian moves and flanks them, and finally make your full attack.

As all of this relies on your party its rare it works (at least is was for me) and to be honest I spent most of my time using move actions to get into place and a single sneak attack. Then I had to survive a full attack sequence from each nearby opponent before getting my full round TWF sneak

Next time I play a rogue I will go the spring attack route having seen other players in my group using it. Is ideal for getting a sneak (flanked) attack in and then returing to relative safety away from your opponents full attack. It takes until about 8th level or so to get tumble to the ranks needed to easily 'fast' tumble in and out of combat

It is a great idea to use your short bow in the first few moments of combat to get in some early ranged sneaks (no feats really needed for this) and then switch to a melee weapon for spring attack

Two weapon fighting and sneak attack probably comes into its own when you get consistent access to blink and greater invisibility but to be honest, i found it hard to use at lower levels and was fairly disappointed about my rogues effectiveness and survivabililty at lower levels

Starting at level 5? Rogue 3/Fighter 2. I've played such a build very successfully in the past. Are you going Human?

If so, I'd take 2-weapon fighting, weapon finess, weapon focus: short sword. Next, grab 2 more feats that add to your roguishness or whatever you like. Improved Initiative can be fun, but with a high Dex, you may be able to skip that if you have other feats in mind.

How far along do you think the character will go in levels? If you're going high enough, taking 2 more levels in Fighter (further down the line, of course) can do two great things for you. One, it can add a burst of HP most other rogues will lack. Secondly, Weapon Specialization for your Short Swords can do nothing but make your foes cry. After that, Improved Critical is a no-brainer. Even if you don't take a PrC and make it to level 20, a rogue 16/fighter 4 would serve you quite well for dishing out some harsh justice, though I would suggest trying to find a good PrC by then.

Skipping out on Spring Attack should work out fine, should you have another capable melee partner that knows how to team with a rogue. The first time you land 2-3 crit sneak attacks in one round will be quite a sight.

Since you mentioned Paragons, that leads one right to Arcane Trickster. I think you'll need 3 levels each in Rogue, Elf or Human Paragon, and Wizard to get there. Not sure which Paragon is better in this case. Elf gets lots of different goodies while Human is better for skills and gets you an open feat. Those d8s will counteract those wizard d4s. Imho, you'll be far more melee viable with Mirror Image and Shield rather than a straight Rogue or Rogue/Ranger/Fighter combination, though your SA will lag a bit.

If you go this route, don't forget about domain wizards in UA. Gets you a free spell/level and all you have to give up is the ability to specialize in a school. Abjuration is probably a good choice.

At higher levels, Staggering Strike (CAdv) is a good way to prevent full atacks from enemies.

Good luck.

EDIT: Forgot about the AT's poor BAB. Eh, oh well.

My first 3E character was a rogue (well, rogue 10/fighter 3 by the end of the campaign). Having a good Con score is pretty essential - I had a 16 Con and it made a big difference hp-wise, especially as I kept rolling low for hp. D6 just isn't that much.

Feats, I had both two-weapon fighting and spring attack. It seemed the fit the kind of character I was going for (quick, mobile, knife-fighter), although I realized that the two don't work well together. You can't use spring attack and attack with two-weapons... it's kinda strange how in order to make use of TWF you need to stay mostly rooted in place.

Watch Flynn as Robin Hood fight Little John with a quarterstaff. That's stereotypical heroic two-weapon fighting, and approximately what the D&D rules are aiming for.
