43 Assassin (all T5 and capstone), 23 Vistani for Celerity and Double Daggers, 7 Harper for KtA, 3 Thief Acrobat for Fast Movement, rest in racials. As you accumulate Universal AP Tomes, Racial AP Tomes and Racial Past Lives, the Halfling racial enhancements pair very well with Assassin (+2 DEX, +3 attack, +3 sneak attack dice, +3 max dodge/MDB).

1 TWF
3 Completionist

27 Blinding speed
28 Tactician
29 Dire Charge

better feats are, dodge, mobility, spring attack

spring attack gives no more attack penalty whilst moving, quite handy i must say. plus a 2% dodge bonus. and a charge attack that does damage to all nearby mobs. great if you are running behind a group with the aggro on them already with the cleave effect and the sneak attack bonus youll be a great party addition

shiv works better than improved feint and does not require a feat.

so for bluffing enemys youll have, shiv, bluff, and diplo when with a group. thats quite sufficient in my experience.

these feat line is more suitible for end game i must add though that I play this line with a full triple completionist.
