@JeremyECrawford where do you stand on the debate between bites doing 1d4 damage? I feel that a bite from a tiefling/human, etc should really only do 1 but my DM is insisting they should be as powerful as a dagger

In D&D's rules, your body parts aren't considered weapons. Some creatures have one or more natural weapons, which are an exception to that rule.

Making an unarmed strike with any part of your body deals 1 + Strength modifier bludgeoning damage. #DnD https://t.co/umVHBPrazm
