Wishing wells...

[wolfing]

nah, only takes one crystal, I always used the well. Most of the time it's money, but I did get a rune once (and I think I got exp some other time and some weapon too)

I got the upgradable baton from a wishing well before. Got it up to the highest of the four levels. I also got some other artifacts here and there. I wonder if that part of the Fan manual has been translated. Worth a look imo.
