Upping damage done by spells

[Burningsoul]

Looking through the fields under Spells_new, I'm guessing I run a query like this... "update spells_new set effect_base_value1=effect_base_value1*3 where effect_base_value1>0;" for spells to hit for 3 times as much. My question is if I run this, will I screw up non-damage spells like summons or buffs? Would it be more beneficial to make an item that somehow doubles the spell strength for each class instead?

Edit: Wasn't thinking outside the box.. could it be under rules as well? I'm looking through the source but I have no clue where or what I'm looking for to change and recompile.
