From the introduction:
These starter rules were written specifically to introduce judges and players to the DCC RPG system. In some areas, rules have been condensed and simplified. These rules will serve primarily to get characters through their first level 0 adventure and their first level 1 adventure. Although the rules go up to level 2, you won't have the full play experience until you buy the core rulebook. This starter document should be enough for you to realize how much fun the game is. For the full DCC experience and play at levels up to 10th, please refer to the Dungeon Crawl Classics RPG rulebook!
