I started in 2020, so I've never grinded out a relic before that wasn't the Manderville set. That said, these really don't seem that bad at all. After getting about half from OC I just FATE grinded with PF for specific colors and got them all by the end of day 3.

It seems people here really don't like the RNG aspect of it, which I guess I can understand, but it really doesn't seem that bad. Sometimes tedious, yes, but... it's a relic weapon. You don't need to get it by the first week.
