Unearthed Arcana (One)
Unearthed Arcana, in One D&D, is a series of unofficial play-test rules, published by Wizards of the Coast for use in home games. Unless they state otherwise, they are not allowed in Adventure League organized play.
“ | You can think of the material presented in this (the Unearthed Arcana) 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. |
