Also allows quick character creation and the creation of template characters. You can also run battles between the characters with special ability support, spells and normal weapon attacks. D&D Manager is designed for Dungeons and Dragons 3rd and 3.5 editions though it may also be suitable for other similar d20 based Role-Playing games.
