Party Areas and Levels

Intro to Camping

 * In FFXI it is very important that you find a camp, and that you find a good one! If you don't find a good camp, you run the risk of placing your party in danger. You may not always find the camp you want, because there is already a party in the camp or your camp simply doesn't exist!

When can I start camping?

 * You would start to camp with parties at level ten(10), and usually in Valkrum Dunes. Although, parting at level ten may be a tad harder then most, since you and your party are still pretty weak. I personally would recommend you get to level eleven(11) before joining a dunes party.

Where To Camp
The following text is not all of my own, I have gathered these resources from around the web and my game community. If you feel that some of these area are not correct or should be removed, please post in the discussions section for consideration. The listings shown bellow are currently of only those more popular areas, there may be other alternatives not shown.

Level 10-20
In this stage you can most likely party in either area without much trouble. Levels of thirteen or higher would be recommended before roaming out into the open parts of the areas.
 * Valkrum Dunes
 * Buburimu Peninsula

Level 20-30
Here is where its starts to go down hill, so to say. Monsters will become more powerful and you will have a harder time taking on a "Decent Challenge", as the zones become more Party oriented.
 * Qufim Island (from level 20 to ~25)
 * Kazham - Yuhtunga Jungle (from level 24 - 27)
 * Kazham - Yhoator Jungle (from level 27 - 31)
 * You will also need the Kazham Airship Pass to get to and from Kazham.

Level 30-40
In the following areas, parties must operate precisely and effectively if they don't want to wipe. Monsters here will aggro and/or link, and are very powerful to those starting in the area. You must also be aware that these areas have 2 or more floors where the monsters usually change and become much more powerful than on the floor above.
 * Garlaige Citadel (from level 32 - 35)
 * Crawler's Nest (from level 34 - 40)
 * Yhoator Jungle (from level 36 - 40) If you really feel the need to explore deeper into the maze that is Yhoator Jungle.

Level 40-50
The going gets much tougher, so be careful! These places can be vast and very dangerous. In fact, if you can't find a camp, find someplace safe to stay while a(meaning one) party member(hopeful THF with Flee and sneak) scouts the area nearby for a usable camp. Dragging a party through these areas is sometimes a dumb thing to do.
 * Crawler's Nest (from level 40 - 50) Again, through the deeper levels and rooms.
 * Yhoator Jungle (from level 40 - 46) It's an awful place...
 * Garlaige Citadel (from level 45 - 50) The lower portions of Garlaige Citadel.
 * Quicksand Caves (from level 44 - 50)
 * Eastern Altepa Desert (from level 40 - 44)
 * Xarcabard (from level 42 to ~46)

Level 50-60
By now, you should know how to effectively party.
 * Caedarva Mire (from level 55 - 58)
 * Bhaflau Thickets (from level 54 - 60)
 * Boyahda Tree (from level 50 - 60)
 * Kuftal Tunnel (from level 52 - 55)
 * Wajaom Woodlands (from level 54 - 59)

Level 60-70
There are effeminately more party locations that this, I just failed to list them because of the level range.
 * Bhaflau Thickets (from level 60 - 66)
 * Boyahda Tree (from level 60 - 70)
 * Mamook (from level 63 - 70)
 * Bibiki Bay (from level 61 - 68)

Level 70-75
At this point in the game, you'll notice a very vast amount of partying locations opening up. Not to mention, you've found plenty of other ways to get experience! But regardless, I'm listing all this for the ease of others.
 * Bhaflau Thickets (from level 70 - 75)
 * Caederva Mire (from level 70 - 75)
 * Uleguerand Range (from level 70-75)
 * Caedarva Mire (from level 72-75)
 * Mamook (from level 70 - 73)

What Else Matters?
During the history of the game, FFXI has made a quite a few changes. Some of those changes affect the attributes of mobs as well as they ways in which they fight. With such changes mingling with things like Level Sync you will find that leveling will be made much easier, given you can find the right camps.

Level Sync and Me
You should know that Level Sync will be one of a few way to gain experience fast. What you should also know is that it can affect your partying abilities later on in game. For instance, your weapon skill level. If you continue to level sync under your level, and to a continued level range (e.g. 27 - 31) your weapon skill will cap around that level range. This means that you're almost voluntarily gimping yourself! Level Sync can make it very easy to level, but you must also make sure you keep your skill levels in check. Please, for the sake of your party take advice from he who states the obvious!

Party Ethics
Communication in a party is the absolute key to survival and victory. This should be a given, in any circumstance with or without a language barrier. A party that does not communicate or communicates improperly is doomed to failure. This should all be explained in the Guide To Partying.
