A few weeks ago, after some discussion among Staff, we were seeing that the use of discs of moonstone was getting a bit too prevalent. These are rechargable female angreal, reducing 8 sps off each weave, 10 charges per angreal.
As the coding for recharging angreal sets the stats to the same discs of moonstone had, it's not currently possible for us to make a lesser angreal rechargable, instead, so we had to settle removing the recharge ability altogether.
