Grim Feast - remnant effect does not apply

Remnant effect does absolutely nothing for the skill, despite Remnant Potency being a recommended support gem for Grim Feast.

I think the chance for double remnant spawn and the Empowering remnants notable do work, but visually it's unclear as it looks like the double spawn happens at exactly the same location so I can't be certain.


As a side note, there's also a slightly unclear (but I assume intended) interaction with Spectres.
Spectres don't leave corpses, so they can't be resurrected with grim feast.
I guess it makes sense that ghosts don't leave corpses, but it is a little unclear as their ghostly nature is only mentioned once on the bind spectre gem and then no longer on the summon spectre skill itself.
