2 PC - 30% increased eye beam damage
4 PC - 15% haste for 10s after using eye beam
Personally I don't see how this is ever going to beat the current set bonus. Even with a demonic build i don't see it matching up. Great set bonuses for m+ but they just seem to be making worse and worse tier sets bonuses for us as far as raiding goes, the only way I see it being decent is if there's a good pad fight with frequent adds where you would be using eye beam frequently due to the CD reduction from raddons or souls.
