Welcome to THAC0 . . . with Advantage! We’re two friends that have been playing D&D a long time. While we both love lots of other RPGs, D&D knows where we’ve buried the bodies.
Sometimes you run the entire night with the assumption that a spell works the way it did from two editions ago, and some poor PCs pay the price. Sometimes the player characters spend three hours exploring something based on what they thought you said, instead of what you actually said. Or maybe what you actually said, instead of what you meant to say. We’re going to talk about mistakes at the table, what they look like, and how to roll with them.
