Ripping off VennDygrem's character from the RHoD, I think I'm going to go with a:
Marrulurk 3/Fighter 2
Feats: TWF (1), PBS&RS (race), Product of Infernal Dalliance (Demodand?) or Otherworldly (flaw1), Combat Looting (flaw 2), Sniper (3), Blitz (Ftr2) (add BAB to damage, but draw AoO), Fiendish Invisibility (invisible in light) (will take at 6th)
So no variants from Dragon magazine and the like are allowed? These are the ones I'd like, but if they're not allowed, that's fine.
Targetteer Fighter (Dr310 pg38) - Skill changes, Vital Aim - Add Dex mod to damage on ranged attacks
Hit and Run Tactics Fighter (DotU pg58) - Remove Heavy armor and Tower Shield prof., +2 Initiative, Add Dex to damage vs. flat-footed opponents within 30 ft (increased to 60' from Sniper feat).
Unarmed Swordsage (ToB pg20) - Gain unarmed strike as a monk of equal level, lose Light Armor proficiency.
Equipment: Ring of Darkhidden, other
Benefits: 3 attacks per round, Dex+BAB to damage (often twice each) with ranged attacks, very sneaky, great scout
Question: Do we get the Tome version of racial bonus feats, like the marrulurk's Point Blank Shot?
