[@Incanus] Great points on the herbalism -- that'd be something to include with the CS for others' use.

As for a lucky charm, you could say that Mat has seemed to have luck in the past as long as he's had it with him, but in the rp I'd rather control its effects as moderator (or at least mention OOC when you plan to invoke its effects IC). I trust you, but it seems like an easy deus ex machina. Also, once again, it may not be what it appears. ;)
