Quell Energy

[Skolos Kopai]

Wondering how quell energy will work on spells that an enemy has already cast but is doing elemental damage over multiple rounds. Specifically, would it stop damage from chill metal.

I'd think that once chill metal was cast the effects aren't connected to the spellcaster any more, if they're killed the spell will continue for example.

By my reasoning if quell energy was cast before chill metal it would reduce chill metal's damage even if the effects occurred after quell energy ran out, but if quell energy was cast after the chill metal it'd have no effect.
