I've gotten two of these from the Grol Baku Taskmaster, yes the Grol Baku Taskmaster you knuckleheads, not a merchant, the Grol Baku Taskmaster! Where does he spawn Arminnius? Where? Prove it! Inquiring minds must know! Well, if you must, he spawns as a rare spawn on the alien island in the Twilight Sea. The eastern island, the one with the higher level aliens than the one right next to it. I was trying to get that Truthseeker's Hammer off the Vas Ren Priest who never ever spawned for me, blasted little Tegi runt. In the process of killing everything on the island and destroying my faction with all the Tegi but the Tegi of Fire (forget their name), I had several odd little creeps spawn for me in the process. I got this whip from the Grol Baku Taskmaster, and two Grey Hide Leggings (Nice Beastlord/Monk Item) from some other little Tegi creep. So there ya go! May Innoruuk have mercy on those little Tegi's souls!
