Can I bring the L 12 medal of Rainbow Island with me?

Medal can only be worn by medals above Grade 8, and can be worn together with wing special effects (golden dragon, butterfly, thousand machines, angels and demons, all professional hallows) and crystal special effects (rainbow crystal, dragon crystal, rose ceremony, star clover, etc.). Well, the constellation cloak is also considered as a special effect column. If it is a medal, colorful colors are brighter than rainbows, but lighter than colorful ones. Everyone has a different eye. I think colorful colors are most suitable for watching rainbows, followed by magic night, third and fourth.
