Can i upgrade uniques in stash that got buffed with patches?

I started again playing weeks ago after years and i wanted to try some builds with old uniques i had but i saw online the uniques got much stronger with past patches. I saw you can do it with a divine but i only played hardcore since forever and planning to still do the same and i never reached level 90 nor i ever found a divine. is there not any other way?

If you mean upgrading them item without using a divine orb on it, no there is no other way.

You can find the unique again or use a Divine Orb IF the patch notes say the legacy versions can be upgraded with a Divine. Usually using a Divine Orb on a legacy unique is considered a "momentary lapse in judgement."

OK thank you for the replies guys
