While playing Origins, I started thinking about runes, and how they worked on weapons. For example, I have "Maric's Blade" with a +2 damage fire rune.
Does that damage come from the weapon's damage (I.E Normal Damage -2 damage +2 Fire Damage) or is it added on? (I.E Normal Damage + 2 Fire Damage)
Also, how does this fit in with spells such as frost weapons?
My "Maric's Blade" has fire rune, and is also Iced, is there any effect to that (such as canceling out), or do I just deal both Fire and Ice damage?
