Test is a failure.
It is very unpredictable, first last night i made a claymore on leveling to 21 st lvl, after sharpening and tenebrium and tormented soul it came out to be 236-381 slash and 71-114 tenebrium 7 percent to crit.
I just made another one mid level, it switched to a flamberge and has damage 204-329.
The first result is craft and blacksmith 5, the second is 4.
Sharpening wheel did not improve the damage on the first made sword but did on the second one.
