Monsters
1. Monster types reduced to a more manageable number. We could probably get along fine with simple types such as natural, magical, and supernatural. Natural creatures have no innate magic and finite lifespans. Magical creatures have innate magic but finite lifespans. Supernatural creatures have innate magic and infinite lifespans. The creature types can be differentiated using subtypes when necessary. Humans, elves, and bears, for instance, would be natural creatures. Dragons, mind flayers, and lycanthropes would be magical creatures. The undead, demons, and elementals would be supernatural creatures.
