There is a Main Scenario quest called Recruiting The Realm.
Unlike most quests in the game, it’s not obvious how to find the folks that you need to visit. Except for Alphi, who is well marked. For the other targets, only the general areas are marked on the map, and especially in Limsa Lominsa, these folks are not trivial to find. There is a page for the quest with a list of the targets with their coordinates, but this is not that easy to use either. So what I’ve done is taken a picture of the mini-map for each of the targets.
I mentioned in a previous post about what happens at level 50 and running the Castrum and Praetorium for Ironworks Armor. And I probably mentioned that it takes 30 or more minutes to queue up for this each day because I played Red Mage or Bard, which are DPS. Well, Silly Me. Healers only wait 5 minutes for these events. Duh.
I have tank jobs, but after you run this, you see that it takes a while to learn the ropes, even as a DPS. There are apparently no shortage of tanks that want to “be in charge” to run this. If I were going to run as a tank I’d need to make a map of the place and have that on another screen. The Castrum is a flat area so that would be easy, but the Praetorium is a multi-level maze, so you really need to learn to run it. I can easily keep up as a DPS or Healer, but I’m not sure I’m up for leading. Anyway, Healer’s don’t wait very long.
