Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Help/Tips/Tricks Tenebrium weapons?

Well I found Sacred Stone.

I can't use any of the Tenebrium weapons because my Tenebrium skill needs to be a 2 (mine are all one). I also can't make any Tenebrium weapons because my crafting isn't high enough (it's a 3).

So ... I'm still without any Tenebrium weapons. Do I need to bring my Tenebrium skill up to 2 and waste the ability points?

Also there were a bunch of Void monsters in the fire ruin area that are apparently immune to anything I have. Do they require Tenebrium weapons?

I'm kind of stuck here.
