You need to revise, to use the Basic Rules for Invisibility Condition VERBATIM: An invisible creature is impossible to see without the aid of magic or a special sense. For the purpose of hiding, the creature is heavily obscured. The creature's location can be detected by any noise it makes or any tracks it leaves. Attack rolls against the creature have disadvantage, and the creature's attack rolls have advantage. Your revised, condensed 'interpretation' of the last sentence is flat out WRONG. DND 5e is worded very specifically, and your wording is easily misinterpreted as to who has advantage and who has disadvantage. Don't overthink it, just use the Basic Rules text VERBATIM. Trust me. Great product overall, would be nice to have a corrected version.
