Together with Dino and Kiere (Dropletz) we went to Aminus 2 days ago. It was less hard than expected (for me) and I wouldn't mind farming Aminus. We didn't get any drops so far.
We ran into Aminus and followed Dino through the halls. He got all monsters behind him and gathered the 3 giants together to the middle. I have no idea how he doesn't get lost in this labyrinth. We killed all the small monsters with AoE skills and then finished the Giants. After that we killed Lykanos followed by Drakul. When Drakul had almost no HP left, Kiere finished it.
