The Extreme quest is supposed to be "Corrupted Boundary" and is the quest that allows you to obtain the class material to make the Effort Symbol ring which is in francas' cafe. Maybe I'm crazy but I'm definitely not seeing it at all, anyone else experiencing this issue?
Here's a link to the JP Release of it http://www.bumped.org/psublog/pso2-jp-a-new-solo-extreme-quest-arrives-on-november-24th/
