I know that Impulse/Force Lore (or whatever I pick to replace that in the enhancement tree) is important.
I know that Corrosion/Acid Lore (or whatever I pick as my pact) is important.

I believe that Maximize/Empower don't do anything to the Eldritch Blast.

Is there anything else aside from Spell Power and [blah] Lore that I should remember to take in order to make my Eldritch Blast more effective?
