Add all your destiny and enhancements bonuses for orbs together, if they're below 71 and you don't have any other sort of insightful spellpower, then the scepters are better and you can spend the points otherwise. But you can also run
legendary fusible kinetic scepter and
legendary flame sphere (The Newcomers) with little problem, though then you lack fire lore, which should be geared somehow.
Or run combustion scepter and kinetic orb and wave the insightful force spellpower.
Also, Cyclonic Blast runs on force spell power, same as Ruin. Force is also for all physical and untyped damage spells.
Without Immunity Bypass, it doesn't change that much, you just choose whether demons or devils take none of your primary damage.
