Guild Wars 2

Hi, i’m new to thief.
I have unlocked all elite specs on it and trying to use staff.
There is this weird thing that I can not understand….does the staff 1 attack once started needs to complete the full chain of 3 hits?
Numerous times during that chain I have tried to use skill 2 or skill 5 for the dodge but some how it completes that chain and then does skill 2 or 5.
Have also tried pressing 5 quickly twice but that just makes the skill 1 chain finish and then does a double skill kitten.
Could you please let me know how you use the staff or point me to a good video?
Thank you.

Haven’t realy took any notice in any weapon set, but I think they all do this. I know impact strike does the same thing when using another skill mid chain.

All chain skills (so every auto and a couple of utilities) will return to their first state or go on cooldown if you use something else. The only exceptions are skills that are explicitly designed in a “you can now use this skill” manner, like Fist Flurry → Palm Strike or Flanking Strike → Larcenous Strike, and those have specific time delays that appear on your status bar.

hey, just put you 1 skill on autoattack ( ctrl+right mouse click on 1st skill ) and now during any 1st skill in chain you can use another one, with out problem. ( sorry for my bad english)
