Can not get second skill set to work says weapon don't match skill and have tried every dagger keeping me from being able to fight
nice, now we just need to know which skill are u trying to use.
You need to see the secondary skill set you are using require what type of weapon. Then choose the weapon in your bag and click secondary. The weapon should be equipped in the second slot and you should be able to fight.

SatThuSiTinh pretty much answers your question. Bro, you have to check which secondary skillset you are currently using, And match it with the required weapon.(may not be dagger)

What you need to do is to check the 2nd skill if what kind of weapon is required, after you checked it, that's the time you put your 2nd weapon if it is dagger, sword, knuckles, etc.,
