Drake scale question dragon age?

hey so ive been playing dragon age and i got to wade and i got 7 drake scales i used 6 to get tha 2 armours but i have 1 extra scale what do i do with this 1 extra drake scale? (its not the dragon scale i have that with me)|||There's not much of a point of the other drake scales after the two armors as Wade doesn't accept them for more armor, and there's no other person that can use them.
