Most Misunderstood D&D Rules

One challenge with Dungeons & Dragons is that players want the rules to match the exciting stories they’re trying to tell. When dice are rolled, people often prioritize a thrilling outcome over strict logic – a roll of 20 feels amazing even though the rules aren’t always that generous. The game’s rules are also designed to keep things moving quickly and allow for flexibility, rather than perfectly mimicking reality, which can sometimes leave players wanting more. Ultimately, each group needs to decide if it’s worth stopping to clarify a rule, or if it’s better to keep the game flowing and adjust the rules to fit their preferred play style.
