How to Scepter as Marauder

So, with the advent of melee becoming actually viable (holy shit I know), I wanted to abuse the shit out of it. My initial idea, and one I'd still like to stick with, is dualing scepters. While this might be easy for some templar build, achieving 100 or so intellect is becoming quite the drag in my quest to Infernal Blows my way to victory.

Anyone care to assist? Is it possible to easily justify the ~+40% elemental damage? Is there an easy alternative to spending excessive amounts of skill points or wasting mod slots on intellect?
