War beast, blue warbeast, depraved, haunting, Fod, Sporvaks revenge, the guilded lord, and The sleeping giant. Just off the top of my head
At your size Warbeasts or ROTWB drops the best, as you get bigger TSG drops quite a few. And in between Haunts are supposed to but hardly do, as with Warbeasts.
recently horn/seal drop from warbeast almost none,after last event.i did send feedback,asking if warbeast still drop seal/horn yet devs still not replying my feedback.
