Have never gotten Goatman Mantle in Briefine but the Goatman Mantle that drops from the Pookhas in Connaught, near Drum Ligin, Has 6 Cha and 6 Emp, rather than 4.
Not only do we get cloaks with designs, but they have good stats, too. No need to get rude with "***** you" because someone asked about a cloak, either.
