Can someone tell me how you spawn Amalagamon. I've done the four dragons you spawn by giving colored gems to the warder's aura, but I can't figure out how to spawn Amalgamon.
One of the earlier bosses in the zone drops a Talisman. I forget the exact name, but the description mentions that it is only for the strongest adventurers and it triggers challenge mode. If you give that Talisman to the aura, and then give one of each color to the aura, it will spawn Amalgamon.
