Facebreaker works with Melee Splash and Double Strike

I wonder if Facebreaker does more damage with Melee Splash and Double Strike?

Those modify skills. They have nothing to do with what equipment you use, other than some skills require certain equipment... bows for example required for RoA. If you use a skill that doesn't require a weapon and is considered an attack, it should work with facebreaker.

Essentially Cyclone and Infernal Blow.
