(Relics) What is the lowest-development-cost content we'd still find fun?

[Morningstar1337]

honestly What I'd do is make it possible to work on multiple relic types at once. If you're gonna do the biggest grind (Zodiac Weapons) and aren't gonna sumplify future relics to compesate for THAT, then the next best thing would be to ensure a way that progress on a different relic type would also count (as an optional path OFC). For example having development on the recetn roulette work in paraellel with progress on a Zodiac weapon (namely the Books)

The other option would be to just tie to Roulettes.

Either way it can't get any lower effort than not having to make new instances :P

Actually, would tying them to a Deep Dungeon work?
