I was wondering what the crap I keep getting for drops is for. Are any of them I am going to be sorry later for not saving? None of them were in the old 9D versions and a lot of them have names that suggest they are supposed to be on North Sea Icy Palace map: Sword of Twin Katana Secret Letter of North Sea Icy Palace Secret Order from Ghost General Abe Secret Order from Hiyami Secret Order from Sky Storm Squad Leader Secret Order from Divine Storm Squad Leader Packed Powder Flask Piece of Ice Armor Whole Musket Piece of Sorcerous Samurai Sword Horn of Spirit Wolf Toenail of Snowman Tail Hair of Snow Wolf Gold Spirit Leader's Plate Silver Spirit Leader's Plate
To my knowledge, none of those you have listed are useful (but I could be mistaken). There are 3 useful drops in LD that I would pick up and keep for crafting into GCM passes. Letter of Yakumo Pieces of Red Clothes Sorcerer's Amulet
Those items are actually for the loyalty exchange materials. They are used to make banner and the materials for banners. However the success rate is very low and it will be much cheaper and easier to just save up for the banner and buy them than to attempt to make it.
