I know that the damange done by a spell is calculated by: base damange*spell power/100 + base damange. But how about weapon rolls?
I want to know, which is the incidence of the rolls (of the weapon equiped) in magic damange.
For example, the weapon have 1d8+4... that roll will be added to the magic damange?... Just the "+4"?... or nothing?
If i'm not proficient with that weapon, will i suffer a -4 (or -25% now it is... no? in that case, 25% of what?) from my magic damange? or doesn't care?
And with two weapon penalty?
Explaining in other words the last... attack penalty by non-proficiency and two weapons are just for physical damange?
