I've been running duty-finder Brayflox groups for 2 days now, attempting to complete the Infantry set. I've heard of plenty of other people doing the same, the Battlemage set seems especially popular. Unfortunately, a lot of duty-finder groups run into problems, particularly on the last boss. I've had so many runs come to an end right at the final boss, and I'm sure anyone else farming this dungeon has too.

So, if anyone else is trying to get these sets, I'd like to propose that we get some Adamantoise players grouped up and running it together! If you're at all interested feel free to post here, or you can shoot me a message in-game (Name: Yaoi Chan). If enough of us are interested I'll even look into throwing a linkshell together or something.
