I don't see a board on this, has anyone figured out how to unlock him as an opponent yet? Not that I could ever get 5 wins against him, but just curious. Someone posted in a news comment that you have to turn in all the amulets at once including the new ones. But how can you turn in the 2 new ones when they come from 5 wins against him? Thanks.

you can get the new ones randomly from doing quentin's quest

Oh so there's 2 ways to get them, 5th win and quests. Just finished Quentin quests but only got 1 light amulet. Thanks. It did seem very confusing that to get him as an opponent you have to turn in something you get from a 5th win against him. Strange.

amulets also drop from random events
