Hmmm... I'm wondering about it too when begin again playing Divinity II wink

Magic Damage

So, every boost on an item of "+ Magic Dam" give all your Spells more Magic Dam .
So, if a melee weapon (or bow) has also Magic Damage, then that weapon help you to increase your Damage using Spells !?
So, in fact, all weapons with Magic Damage on it ... does for itself NO extra magic damage by using that weapon ??? confused

But the more a weapon has Magic Damage (and other equipment have boosts for this Magic Dam!), the more it strengthen all your Spells like Magic Blast, Fireball, etc ... ?
(but also ONLY the Mage skills, not magical skills like Healing or Stun Arrows or Rush Attack or ... ? )

Another thing:
are all "Armour Ratings" on equipment the same as "Resistance/Protection" ?
So, for example : Magic Armour Rating == Magic Resistance ?? )
But I'm totally not sure because Armour Rating is showed as a number and Resistance is showed as a number in % !
If both ar indeed the same, how do they correspond with eachother?
For example: 1 % in (Melee/Ranged/Magic) Resistance == X - amount (Melee/Ranged/Magic) Armour Rating

Hope someone know more about this? I examine it .. but can't find an answer ...

On 7th of february 2015 : I start a new adventure in the Divinity world of Original Sin,
