What scaling does it have at +5 if anyone knows? At +0 it has very weak strength and skill scaling at E and E. I'm guessing right now it scales as a really terrible "quality" weapon with an electric buff that does all the damage.
But that arcane does nothing for the weapon? Yeah that needs to be fixed.
It is odd that all weapons in the game have some kind of arcane scaling just like they do in BB but that was because you had blood gems to give weapons damage and scaling with fire, bolt and, uh, arcane but there's nothing like that here. The arcane scaling letters probably should be removed from all weapons except ones that do non-physical damage. If this ever gets fixed, Tonitrus should have just Arcane scaling and not the weak strength/skill (since the weapon does no phys damage anyway) and so on.
