Below you'll find a list of hotfixes which address various gameplay and service issues affecting Diablo III. Hotfixes are updates we make on our end without requiring you to download a new patch. Some of the hotfixes below will go live the moment they are implemented, while others may require a restart to go into effect. Please keep in mind that some issues cannot be addressed without a client-side patch update. We will continue to update this thread in the days ahead as additional hotfixes are applied.
