I don't mind the Tenebrium skill, but it really should only increase THAT damage, I agree it hurts the player (you can even add Tenebrium to existing weapons and the damage is the determined by that skill).
Aside from the silly weapon visual effects and the last boss destroying the npc before you act (occasionally) I have zero complaints about this game, and honestly I'm not ALL that frustrated with the Tenebrium skill - I just think it is a silly concept.
