Yupp found that one too some days ago, searched all over it while fighting fampyrs, unfortunetly no antler there, that's why i started this topic, cuz i couldn't find enything in the web about that darn antler.
Please, for the love of all the false gods of eora, can someone tell me where i can find ingredient: antler, somehow it is eluding me, and i can't enchant the "Ball and Chain" flail, to complite my stunlock assassin build
