Nymphs arnt't extremely unobtainable and rare.(unless im just plain lucky which i usually am not when it comes to chance)..ive got 8, just get to the oracle every day, patience
Yes i agree with Barragor, I have gotten many things from spins after winning. Also when people in chat or something i hear them often complain about the oracle 1. the oracle doesn't require any effort other than logging in to use so don't go complaining when you don't get something. 2. I Don't often log in, when i do i tend to play a lot, but not too many days, and i still have 6 nymphs from the oracle, so it must not be THAT rare (i hardly ever get lucky with rare things in games) to complain about.
