Adding challenge log for older Deep Dungeons

[Aidorouge]

I wonder though what could be good rewards from the log to make them interesting in the long run and not simply "get rewards and don't go in ever again".

A special kind of item (or a unique currency to buy the item via nearby vendors) that can be applied to any Deep Dungeon's aetherpool weapons/armor (including future ones) up to a certain level?

It might encourage people to try ones outside of Palace of the Dead and Pilgrim's Traverse if they can give themselves a little "head start" for the ones in-between or to make working on a new grip less daunting, but not let them outright max their weapon or armor, they still need to actually go in and do each specific one to reach their respective aetherpool cap.

Maybe even make the item tradable so there's additional value for those who don't need it in the same vein that some people profit from farming logos/lost actions in Eureka and Bozja.
