How does cover work when one side has no LoS? (Ricochet, Marked state) Do you still need to have an adjacent space Blocked or Occupied that would obstruct LoS? For example, what about these 2 situations where Defender is either Marked or Attacker has Ricochet on: and Can the Attacker get cover when defender is Marked? What about if the Attacker is using Ricochet? Marked state, unlike Range (which has the rule that all cover rules are ignored) doesn't say that your attack is , it just says that you don't require line of sight.
