paragorn, reliquary tender, and frozen banshee are all worth keeping and you it's worth hanging on to a copy of the rares you need for the relickeeper fusion as well. you also might want to hang on to athel; she's decent enough that you'll likely find a use for her at some point (even if only for faction wars and dt secret rooms) and the one you have is already awakened. speaking of, stop awakening champions that you aren't actively using. outside of those, you can go ahead and use the rest of your rares as food.

"speaking of, stop awakening champions you aren't actively using" 😂

I don't know what I'm doing so thanks for telling me lol

Oh, I already did relickeeper fusion.

Just also keep in mind that with cursed city, some of those rares will find new value. Using one as food only saves you about 100 nrg, so I would just save one of each if you have the space.

That's a great point. Thanks!
