New question: should we retool Category:Poisonous Creatures, Category:Ice Creatures, Category:Fire Creatures, and Category:Electrical Creatures? It might be difficult defining these categories, but again, we don't have Category:Water Creatures, Category:Earth Creatures, or other elemental categories. I suppose Poison, Ice, Fire, and Electricity are the most notable elements, especially in the RPG games.
Although I feel that Poisonous Creatures is inadequately used (I'm sure a lot more enemies in the RPG games cause poison), that's something that can't be solved with a little bit of work. I do, however, think that these categories can be retooled to serve the enemies that cause poison, freezing, burn, and electricity (and they don't necessarily have to cause a status condition in an RPG, but a category on that would also be helpful...)
