This is my first build posted, open to criticism and comments. I tried to make a “hard-to-hit” character, while able to deliver devastating critical. Here it is.
Rogue/Bard/RDD (29/1/10) Elf (necessary) Chaotic X (necessary for bard)
1: dodge 3: finesse 4: +1 dex 5: bard (useful for shield since this character does not have the available feats for dual-wielding; and keep some skill points from rogue to invest in spellcraft (I put 10 in total for saving throws bonus) and discipline) 6: RDD/ Weapon Focus (rapier) 8: +1 dex 9: Power Attack 12: +1 dex/ improve critical (rapier) 15: cleave 16: +1 dex 18: great cleave 20 +1 in strength (important for crits feats) 21: overwhelming critical/ defensive roll 24: +1 dex/ devastating critical/ improve invasion 27: Great dex/ epic dodge 28: +1 dex 30: great dex/ opportunist (or any other rogue feat) 32: +1 dex 33: great dex 35: self-concealment 36: +1 dex / self-concealment 39: self-concealment/ self-concealment 40: +1 dex
So this character finished with 40% of concealment, Epic Dodge, devastating critical, and a naked AC of 33 with good sneak attacks. I maxed out move silently, tumble, open lock. Almost maxed out were hide and UMD. I also invested in discipline and spellcraft (as mentioned above). Versatile and fun character to play, especially online where you can easily buy high-level spells (from stores or other players).
