Lanne and Jelta are being picked on at school because their clothing isn't fashionable enough. Help the girl from your faction (Lanne is in Elysea, Jelta is in Asmodae) and give them this headband, decorated with yellow flowers. It will definitely turn them into young trendsetters! This item is free and will be required for the completion of the "Ahead of the trends" Elyos quest as well as the "Just One New Thing" Asmodian quest. One is more than enough: you will not need to assign it many times over.
