precursor's emblem ring question

does x to x lightning/cold damage added per power/frenzy charge work with spells?
This https://www.pathofexile.com/forum/view-thread/2232595 and this https://www.pathofexile.com/forum/view-thread/2656062 say it does, but as far as I know it doesn't?

Yes.

Because it doesnt say 'to attacks/to spells', it applies to EVERYTHING.

compare:



steel ring says attacks. circle of regret doesnt. circle applies to everything.
