Yes, Tenebrium isn't really resisted by much, and it tends to be the lowest resistance on things that do resist it. That still sounds more like a case of "enemy resistance tweaking needed" to me, but that is a point.
Not really, it's the entire POINT of Tenebrium.
If you don't get that and just brush it off as "must be a bug/bad balance" then I can see why you would say the things you did in this thread.
But fact still remains, it's not a balance issue nor a bug.
That Tenebrium was Single/Double/Ranged all in one, THAT was a balance issue. And it has been fixed. I say 'thank Larian for that'...
Also for above poster saying points are wasted, nope; that was the old system where any not in Tenebrium were wasted. Now they're NOT wasted, and any of them still count when using Tenebrium weapons. So basically they fixed what you're complaiming about.
Which makes ME go 'whhhaaaaaat?'
