What exactly does leveling a particular weapon skill from normal attacks do? I am talking about the Weapon Skill tab when you hit "C". Just curious.
For the most part, it increases your weapon accuracy and, therefore, reduces the number of times that your attacks miss the target. But...
It's useful mainly for melee or ranged *physical* DPS damage dealers and not for spellcasters. If you happen to note the skill listings for Wand and 2H Staff, those will display the skill level for *physically* hitting an opponent with the weapon and not the accuracy skill for hitting an opponent with a spell.
This is another reason casters are behind other classes, as we don't get any skill upon good casting, where mele classes do get skill level rise upon good hits.
I'm not sure if adding Wand or 2H Staff *spell* accuracy to the weapon accuracy list would unbalance what we already have. I'd tend to be against it since *adding* that accuracy might tend to cause physical damage dealers to scream for nerfs.
