D&D characters experience time very differently than we do in real life. Their world takes place in distinct 6-second rounds. How they can behave during these 6-second rounds is controlled by which part of the round the universe is currently in. As a player I have frequently witnessed the poor adjudication of Surprise Rounds, which is very understandable as the Surprise Round takes place in a weird moment in the already hard to fathom flow of D&D time. Beyond the problem of conceiving time in D&D, I think a deficit exists in the Surprise rules of the system, which takes Surprised to mean “has been successfully ambushed.” Due to this deficit, it is my opinion that DMs often intuitively but unknowingly house rule the Surprise Round rules to fit a variety a situations that the actual rules do not address.
