So, has anyone come far enough in this game to see/find how the tenebrium weapons ability applies? Does it stack with 1h/2h? Are there tenebrium daggers for rogues?
I'm wondering because I don't know whether it's a waste to sink 15 points into single handed if I'm going to use tenebrium weapons eventually anyway.
It should stack with 1h/2h. You can coat normal/magical daggers with Tenebrium if you have the proper crafting level and the Tenebrium ability.
But don't worry, at a certain point in the game you learn Tenebrium level 1 for free and you can use Tenebrium weapons afterwards without a downside.
