A key part of Dungeons & Dragons' ruleset is missing from the new SRD, limiting what third-party creators can do with the new system. Today, Wizards of the Coast released the System Reference Document (SRD) 5.2 under a Creative Commons license. The document provides a portion of Dungeons & Dragons' newest ruleset for third-party creators to use and reference when creating their own material. This functionally creates a framework for third-party Dungeons & Dragons material, setting the tone for the supply of new releases that will support the game in coming years.
