Yes, players who have passed during the round can still gain benefits from other players' turns, as long as the benefits are triggered by abilities or effects that involve all players. The rulebook specifies that card abilities are optional, and if an ability gives an opponent a benefit, they may gain it even if the active player declines to do so (Page 6).

How Order Impacts This:

• Turn Order During the Round: Play proceeds clockwise, and players who have passed do not take further actions. However, they remain eligible to gain benefits from abilities triggered by other players during their turns.
• Round End Abilities: At the end of the round, "once per round" dragon abilities are activated in turn order, starting with the round's start player (Page 14). If a dragon ability presents all players with a choice or benefit, players make their choices or gain their benefits in clockwise order, starting with the owner of the dragon.

Summary:

• Players who pass during a round can still gain benefits from abilities triggered by other players during their turns.
• Turn order impacts the sequence in which players gain benefits from "once per round" abilities at the end of the round.
