It is very UNCLEAR wether an expert quality longsword with a +1 weapon potency rune needs to be invested.
It is clear that an expert quality longsword with a void rune must be invested if the user wants to activate the weapon. But according to everything that I read the user gets the void bonus without activation - just not the activated part.
It seems that there has been a lot of controversy over resonance points. If what I am reading is true, a character can have the use of worn rune enhanced weapons and armor that do not have activation costs without investing any of them, and consequently not using any resonance points.
