A GM can take away your Ronus boots.
The Gem of Rememberance is an important developer object that stores certain variables about your character, so it must be kept.
The PC Dicebag and Emote Wand can be taken away by a GM as well but the system is coded to check if you have them when you log in and if you don't it gives you them so there is no sense in removing those either. Perhaps the community can decide whether they're needed any more and remove them if not.
Just as an addendum to this I've added the following command
=c noneed item
So far acceptable items are:
This will destroy the items and you'll not get them when you login with that character again.
If you can think of any more let me know. No, this won't work with the PC Properties skin unfortunately. Looking more into that.
Although Charles is quite generous and his gift is quite nice, I'd like to donate it to "gods".
