Runes of Magic US / AU

Damage that is deprived from the magic damage of your weapon. It is shown just under the physical damage it does.

Magic damage is calculated seperately from physical.

Magic damage is gone through with Magic attack
Where as Physical damage is gone through with physical attack.

Thats why all weapons have both magic damage and physical damage. Magic damage has no part in melee attacks or auto attacks. but in part with spells and attacks that inflict elemental or plain (none elemental ) magic damage.

I dont know the exact formula. But its the most important part of any spell. it takes precedence over the base damage of the spell in the tooltip itself.

Its easiest to look at it the same way you would look at phyiscal damage and attack power. On difference is your skills use dps%, which is a modifier. Just recently in chapter 4 spells were getting a modifer to conpensate (x INT in spells. Some spells dont have it). So its all mostly balanced now but thats getting further than what needs to be.

Just remember damage takes precedence over all your skills. THen look at the attack stats, since that basically tells you how much of that damage hits pass the opposing defense.

Basicly, the more Magical Damage you have, the harder your spells will hit. I don't think it "adds" to the spell damage. But it affects the damage in ways that are incomprehensible to most of us lol.
