Welcome to the first installment of Unearthed Arcana, a monthly workshop where D&D R&D shows off a variety of new and interesting pieces of RPG design for use at your gaming table.
You can think of the material presented in this series as similar to the first wave of the fifth edition playtest. These game mechanics are in draft form, usable in your campaign but not fully tempered by playtests and design iterations. They are highly volatile and might be unstable; if you use them, be ready to rule on any issues that come up. They’re written in pencil, not ink.
The material presented in Unearthed Arcana will range from mechanics that we expect one day to publish in a supplement to house rules from our home campaigns that we want to share, from core system options such as mass combat to setting-specific material such as the Eberron update included in this article. Once it’s out there, you can expect us to check in with you to see how it’s working out and what we can do to improve it.
