What's Better, Raw Spell Dmg Or % Spell Dmg

I want to make an endgame build with decent damage, but I'm not sure on whether to get more raw or % spell dmg.

 

Raw makes each of your spells do the amount of raw spell dmg you have.
% works diff, depending on your raw spell dmg it will increase the dmg

1000 raw spell dmg and 100% spell dmg=2000 spell dmg

 

Do they stack?

 

Salted posted the equation back when raw got nerfed. It goes something like base damage plus modifiers (like skill points) times any +%spell damage, times the wands innate attack speed modifier (no longer adjustable by items that + or - attack speed, but still using the wands built in speed), then raw is added at the end.
So if you have soul signal adding 300, and jester adding 200 (?), and uh, some other raw stuff, you add maybe a 1000.
If you are using Az, and are adding 100% spell damage, and roll well...

The answer is actually probably based more on which class, rather than your build/main weapon. Mages do little base damage, a steady lump sum of raw will often be better. An assassin or archer with a good weapon will probably do better with a focused build and %.

It is similar to the question of whether a build focused on one weapon that does one element damage is better than a rainbow approach to attacking the mobs weaknesses. I find mages damage is low enough the element weakness of the mob determines the best way to attack.
But I was lucky enough to find an Az, my archer is all about maximizing thunder damage, thunder resistance be damned.

 

Thanks. So if I'm a mage, I should go for raw spell dmg then.

 

No, %. Raw is a raw bonus, % is a % bonus on everything except raw.

 

On Mage, you want to focus on %Spells, as your spells usually only hit 1 time. Raw spell is op for assassin cause of multi hit hitting 10 times

 

See, there are so many moving parts it is open to personal preference. Try a little of both and decide for yourself.

 

Thanks!
