From now on, any change to a clan's prac bonus will have to be paid for through the treasurer, for a sum of 20,000 gold crowns per change.
As it is, players are switching willy-nilly, usually to something that is not quite as rpish as what this feature was intended for. Ergo, it will now take some effort to get your clan prac changed.
