Has anyone made a Formless Inferno & Dark Pact build?

I'm curious to see if it works

Many people league-started it because when Formless Inferno was revealed, it said 'uncapped resistances' (which is your final resistance number, ignoring hte max resist cap), but in game it's actually 'overcapped resistance' (which is uncapped minnus 75% basically). This was enough to move it from a compelling interaction to low-value synergy.

It 'works' in that it does increase minion life and therefore Dark Pact damage, but it 'doesn't work' in that it isn't good enough to build around.
