You can go in at what levels?
IIRC the minimum level is 17.
Is it better to enter with a lower job than a 60?
Depends. Going in at 60 gets you seals but going in pre-60 gets you exp similar to roulette. You can do it multiple times a day though so it's actually a pretty good way of getting exp, especially for DPS jobs because queues are so fast.
Can this be done with Just Tesee and I?
Maybe. Depends on the jobs. You don't need a full party. It can even be done solo if you want. It's balanced around 4 people though, especially the higher level floors. Two people can definitely do the first few floor sets, especially if one of you is a healer. You might have trouble with the time limit on higher floors though.
Where do you get the aetherpool armor, i do not see it in the patch notes?
Aetherpool armor isn't an actual set of armor. It's just a number. While the weapon looks different and can eventually be used outside of the dungeon, the armor is really just a stat.
I am guessing this is not end game content?
Not really. You can get a i235 weapon and grade V materia out of it, but the content of itself isn't considered endgame.
Can you get any end game drops in here?
If you get the weapon and armor to level 30 inside the dungeon you can then use the weapon outside as well. It's i235 so it's actually a pretty easy (if a bit time consuming) way to get a high level weapon.
If you go in with two do you have to finish it with two?
I think so. IIRC if you go in solo or as a party (as opposed to with random people in DF) you have to continue with that same party. That said, you have two different "save slots" so if you want you can start a second run with randoms or a different party without losing your progress. You can also reset and restart from floor 1 without losing your weapon/armor upgrades.
Can anyone explain this better to me? We have not played much at all the last 6 months so a little lost now.
Palace of the Dead is a 50 floor, randomly generated dungeon, with a boss and a checkpoint every 10 floors.
Levels inside the dungeon are completely separate from the rest of the game. When you first enter your levels are reset (temporarily) and you start at level 1. You level up and get all your abilities back as you go through the dungeon. Even if you go in pre-60 you'll still get access to all the class and job abilities at the appropriate levels. (e.g. a level 40 BLM will still learn the level 45, 50, 52, etc job abilities even without having done the quests.) However, if you go in as a class you won't automatically get the job at level 30. You'll be stuck as the class the whole way.
The other big thing is aetherpool weapon and armor levels. When you enter you're automatically equipped with a weapon and armor. As you progress you'll come across silver chests, which have a chance of upgrading one or the other. Weapon/armor progress is saved independently of your floor progress and is the same for all jobs. If you go in as a DRG and get your weapon to level 4 and then restart and go in again as a PLD, your weapon will still be level 4. Once you get both the weapon and armor to level 30, you can trade them in for an i235 weapon of your choice. Doing so resets your equipment back to level 0 but you can start over if you want another weapon.
We finished patch 3.3 except we need to unlock the last dungeon?
Have you beaten and finished the quest for the level 50 Hullbreaker Isle? That may be a prerequisite.
