Quaestion about Assassing Dagger Attacks

I've been meaning to ask this question for a month now, is there a way (or a title) that decreases the probability that an assassin lead or offhand attack (like jagged strike or wild strike) will miss upon execution of the skill?

Lol, I have NO clue what the purpose of this thread is? Doesn't the lead attack ALWAYS hit, since it's a LEAD attack...

You probably miss alot, because u never check the hexstack thats on you... Check fro hexes such as; Blurred Vission, Reckless Haste, Price of Failure, ...

Lead attacks missing "spontaniously" is something new to me rly :s

In guild wars your attacks will always hit unless you Blind or a hex that causes missing on you. The only other thing that may cause it is if you use an attack that requires a Lead Attack without actually using a Lead Attack.

Then what does it mean when a spell like Jagged Strike stateds, "If this strike hits...." [skill]Jagged Strike[/skill]

It means exactly what it states. If it hits then it will cause bleeding.
There are several reasons why it would not hit, like various hexes, condition blind, various enchantments and stances. So if one of those causes it not to hit then it won't cause bleeding.

Alright, I misunderstood the if it hits, as, this attack will miss a certain percentage of the time.

Thanks!
