Ty should i still upgrade or keep Quick Strike, Rend, Smoke Bomb, Sneaky Attack??
Ditch quickstrike and rend and go with a dex/str build. I'm hoping that some skills might be changed a bit after the update releases, but for now I can definitely say, do not use quick and rend
Ty so ditch qs and rend and put points in reflex and poison wep??
That's what I would recommend. As mariner said, QS ain't so bad, but...
The way you asked about a golden dagger makes it seem like you have one. If this is the case, then QS wouldn't be near as valuable than if you have normal gear.
