Idea is simple, I ofc have no idea what actually is needed to change a gender for a character... but as it is possible after retirement, it doesn't seem to be that much of effort, does it?
What about making it also possible any time? Of course for a payment of gold. I want my main character not to retire again, I'm fine with staying with my build and got enough looms for it so I plan on lvling higher than level 30/31. However I know myself and wish to change my gender from a female character to a male character at a certain point in the future. That however is only possible by retirement.
What about making it possible for a payment of let's say 20% of the current wealth in gold (and at least 100k gold if the 20% are less than 100k gold). Those numbers can surely be changed (or be totally random in every single case).
edit: Good Idea, Ayween!
