Brass Knuckles q.7 Dagger Mastery

hi im not sure if this is in the right place, but oh well.

i got nightfall about a year ago, and dont have proph or factions. i also got eotn, and did the quest where you win some better brass knuckles. they have q7 dagger mastery but i can change to sin as my secondary because i dont have factions. is there any way of getting round this?

Nope, you'll have to buy factions.

And the daggers aren't req7, they'r req9.

ok thanks anyway
