I have killed Aleister 3x now, and no horns. I don't see them in the room as an item to pick up either. Any help is appreciated. Thank you!
Yeah, it's a random chance. I got mine after 4 kills. The quests for LoT are generally very frustrating, requiring many clears to complete. The best are the second and third tier of quests -- right now I have one that is asking for 10 of a trash mob that only appears once in the dungeon, and one to kill a hidden boss that is only accessible through random chance. So far I've done 8 clears and have not been able to get to the target for this quest (Marineu) -- he is hard enough to find that I haven't actually been able to find a single player in game that has seen him.
