This is a post in regards to some of the arguements in Exile about invisibility and readied actions. I posted online at paizo's forums and this was the resulting thread if anyone is interested.

Thanks

This is good info Mischief, and well done crowd-scourcing a rules discusion. That said, neither of the people directly involved with that debate will see this post.

yea, but its still nice to have. if it comes up again, we have another reference

I understand the point at issue but I don't understand the resolution.  What is the answer?  (If this comes up again, what would we decide?)

Sorry, was browsing old posts and noticed you had a question unanswered, Opal.

Long of the short of it, a Fighter knows what square he is attacked from by the invisible attacker. The ninja strikes him, the fighter gets his readied action. Due to the fact that the fighter is unable to know the attack is comming before the attack resolves, his readied action happens after the hit (so the ninja did enough damage to force the fighter unconsious, he would not get his attack), but his initiative is just before the Ninja's.
