The type of motif page you will gain will depend on the boss-type: Dremora Motifs are tradeable, so you don’t get the one you want you can always swap with someone else. While these will contain the same items found in regular plunder skulls, you are guaranteed to gain a new Dremora Motif page depending on the boss you conquer. You can gain a Dremora Plunder Skull the first time you defeat each different type of boss each day.
