A True and Perfect Knight

Two halves: a rank-6 accolade, and its acclaimed knight carrying Crusader, Mujahid or Warrior of the Faith (any of the three counts). Accolades gain glory from battles the knight fights in, so the wiki recommends an 867 Norse start - +20% accolade glory from culture and faith, and endless raiding for battle volume. Farm to rank 6, always keeping an accolade successor appointed so the rank doesn't decay. For the trait, either convert and join a Crusade (send the knight to fight in the target kingdom), or reform a faith with Armed Pilgrimages and declare your own Directed Great Holy War - you don't need to WIN it, the knight just needs to fight there. Known wrinkle ("In Review" at Paradox): accolades can merge messily on succession and block the rank-6 reinstate - freeing accolade slots and reinstating the knight has fixed it for affected players.
