Here are the horns only from the Tera Succubus, as of the set is being worked on by another person. The Ultima Horns are for every race just move them however you like to, as of the base item is not easy to get unless you more or less spend a few days camping for that fate in azys lla. They are darker then the original ones to better fit my personal style so keep that in mind.
