There are magic swords. There are patrons. There are even more tables for making monsters unique. There are rules for making cleric deities more distinctive. There are rules for patron weapons and magic rings. There is the lost continent of Mu, and the hidden places between worlds. And there are rules for magical moustaches. You absolutely do not need the DCC Annual to play DCC RPG, nor does any material in the Annual supersede or otherwise change the baseline game experience as expressed in the core rulebook. There is no rules bloat: only new vistas of imagination.
