Crippling strike in Pathfinder Roleplaying Game Core Rulebook (OGL) Hardcover

[sempai33]

I wish to know:
"An opponent damaged by ONE of her sneak attack also takes 2 points of Strength damage"
Does it mean that this advanced talent can work only one time on an opponent during an encounter ? Or during a full round action (with at least 2 attacks) the rogue can use it only one time by round ? Or during each round, a rogue can use this talent and make 2 strength damages each round ?

[Dilvish the Danged]

I don't know of any rules that prevent the Strength damage from stacking/accumulating on an unfortunate target. I am fairly sure that the victim would suffer 2 Str damage per sneak attack.

[Quandary]

1 successful (sneak) attack -> 1 application of crippling strike effects

if the author meant something works 1x/round, he would have written that.
(other powers, like Barbarian Rage, do indeed have explicit 1x/round limits)

[Kvantum]

If you let the two-weapon fighting Rogue flank you, then yes, you can end up the victim of six sneak attacks a round and take 12 Str damage a round. (Assuming the Rogue has a BAB of +11 or greater, Improved Two-Weapon Fighting, and a Speed weapon)
