I've actually been wondering this for a long time, and I figured I'd post my thoughts here since there's fuckall on the motherboards about it.
As many others are wont to do, I often run Chamber of Raiyum EN twice a day for the exp while going through my Epic Reincarnation grinds. Of course, because of the way that ransack works, I tend to wait at least 18 hours before beginning the next day's runs.
The quest base exp itself seems to reset, but for whatever strange, stupid, turbine reason, the optionals don't. I always do every optional, but usually, the exp yield works out to something like this by the next day:
- Base exp is fine
- Hami is -60%
- Hafez is -80%
- Akvan and Mehrdad the genies are at -40%
- Treasure chamber is at -100%
- Eternal guardians are at -60% or something
It makes absolutely no sense. I also run VoN3 and Spies every day twice, and
those optionals always reset by the next day. So what gives with Raiyum? Did the devs somehow fuck up this one quest? Is the optional ransack timer just
broken for this one quest? Perhaps someone more knowledgeable can explain to me what's going on because even by Turbine standards, this one's pretty baffling, and I'm genuinely curious about it.
