Hi, everyone and happy new year!

I just have a question about the quest the Clerics of the South give you to improve your stats. First you have to become worthy by ringing gongs. Do you have to do this just once to be able to reuse all of the stat increasing places or do you have to do it again after you've visited all of them? If someone would explain in detail how this quest works and what do you have to do to keep using the stat increasing places it would be very much appreciated. Thanks!

As far as I know:

_You get the stat increase once before becoming worthy.
_You get the stat increase once again after becoming worthy.
_I'm not sure you can repeat it again after this.

You can repeat it as often as you want (at least I could in NES version).
