So how does one go about expanding the Urban Druid spell list? It only contains spells from the PHB and Dragon Compendium, but there's tons of spells out there in other WotC products and Dragon Magazines.
It'd be nice to get an expanded spell list for them, or suggestions on what spells to consider to add to their spell list. This is why I hate unique spell lists, expanding them takes careful consideration and time and varies between games. A spell list set in stone would be better, for example the Spellthief class allows it to only gain access to spells from specific schools.
I think more classes should follow this trend. It's a real pain trying to expand the Urban Druid spell list, and others, such as the Hexblade's and the Duskblade's.
