Final Fantasy XIV Content: Bozja Southern Front. In this part of the game, there are 1v1 duels you can fight in for an achievement, title, and 99 lockboxes for loot. Getting chosen to participate in these kinds of fights are pretty difficult- you can't get hit ONCE by any dodgeable damage in the previous Critical Engagement that activates the duel (it then chooses one player out of the group that actually did this). And almost all the mechanics in the duel will kill you if you mess up. I got lucky and was chosen. I was way too nervous to even dps efficiently, but somehow it worked out.
