That reminds me of a question: what are tenebrium weapons for?
I just finished the game, I never found one that'd deal more damage than my usual weapon, and more importantly I never had to use them, though at some point I remembered it seemed important for a reason... I just can't remember.
Tenebrium weapons might have a similar base damage as your regular weapons, but they will use the Tenebrium skill for bonus damage calculation instead of the weapon skill. Since you can get a passive +2 Tenebrium bonus (quest+book) and a +3 bonus from gear you can double that base damage while the regular skill is capped at level 5(+2 from gear) ->only +70% additional damage.
While the Tenebrium weapon at the store might not compare favorably to your legendary weapons, you can simply enchant them with Tenebrium and they will use the Tenebrium skill as well.
The second bonus of the Tenebrium skill is that it will apply for weapons of any type, so if your Scoundrel wants to switch to a Bow, he will get the same damage multiplier, or think of a tanky Warrior with Shield that can switch to a big 2H Axe (or the other way around).
