Hey, so you're going for platinum well you'll definitely have to start ng+(new game plus/new cycle) for plat. Anyways you'd mentioned the lantern curio. To get that all you have to do is takeout all 9 of those lantern face guys. It's four of them on the same floor, not a step higher but, on the same floor as the Lower pagoda shrine.. then four, not a step below or higher but, on the same floor as the Upper pagoda shrine.. that would make 8 in total. The last one you go to the Mani Wheel Shrine &, instead of going towards- where the boss would be -you go back the other way(towards bridge) but keep going further towards the falcon fight. Should you run pass him there's a "drop down" & on that floor is number 9. Keep in mind they only appear when your eyes glow red or screen in twilight mode. Yes you could wait for the screen to go twilight to make sure you've gotten them all. Congratulations on defeating Sun Wukong."🕹️👑🎉
