@JeremyECrawford #DnD rule Q: Can players use the ready action before initiative is rolled (essentially guaranteeing a free surprise round)?

The options, including Ready, in the "Actions in Combat" section (PH, 192–93) are meant to be used in combat, after rolling initiative. #DnD https://t.co/wqqKrtZw2t
