Spell Damage Question

Is + spell damage % much much better than + spell damage (number) ? If so does it mean I should always take armor with % over those that only give a constant amount?

 

Varies. As a rule of thumb, mage and warrior are more partial to raw while archer, shaman and assassin are more partial to percent. If you want to know for sure, you'll have to calculate it (as I explain in the Classbuilding 101 guide linked in my signature).

 

combining a high % spell dmg plus a high flat amount of spell dmg is most effective for sure

 

Spell damage % is most effective in combination with weapons with high base damage and attack speed. Raw spell damage is most effective on spells with a high damage multiplier, such as meteor.
