The first thing I thought of was Pyromancer with Salazar’s Blade (which does substantial Chaos damage and gives up to +4 points to Summon Familiar with the right prefix), Primal Instinct, and Occultist Conduit that lets Summon Familiar pass through enemies (somewhat makes up for not having blocking bodies). You can get 26/16 Raven, 22/12 Hellfire, and 22/12 Flame Touched, but you end up sacrificing too much damage and you end up having poor pet damage, even with the bonuses from the above + Storm Spirit. If I was playing Pyromancer, I’d call for at least 2,000% pet Fire damage + Mogdrogen for over 100% total speed, but the equipment that gives you the best skill points unfortunately skimps out on pet damage, so you have to choose between getting the skill overcaps or getting enough pet damage. I’m not optimistic.
Though it’s green-tastic, I think the Witching Hour build will turn out the best, especially since Raven going full 26/16 might end up overcoming the loss of Dying God and the pet Chaos damage.
