This is probably a dumb question, but I can't find the answer anywhere else. When I join a party, we have a limit meter, right? And when it fills up we can use a limit break. How do we actually do that? Like, what button do I press? Do I click something on the screen? Is it something only the party leader can activate? Someone help me out here.

Also, once the duty's over and we've cleared out the dungeon and everyone else has gotten a chance to roll on all the gear that I can't use, how do I actually leave the party? I can't for the life of me find out where that command is.

Thanks.
