@JeremyECrawford Do you become non-hidden the second you pop out of cover to get LOS on your attack? Or only after the attack?

You’re no longer hidden the moment your attack hits or misses. #DnD https://t.co/TVHN1vDdlT

@BitghostxSo if I ready an action, the trigger being when an enemy reveals himself to attack, that reaction happens AFTER his attack? Yes, because you included the attack in the trigger.
