Scouts report that the new Mamool Ja soldiers have received supplies from their families. Destroy Mamool Ja morale by stealing these supplies while being careful to remain undetected.
Open coffers and give the items in them to the NPC at the start without getting caught.
The starting point, the Rune of Release, and your contact NPC Quhaaja are all in the same spot at the north side of the map. You must bring the items to her.
All Mamool Ja are true sight, but you can use Viscous Liquid barrels to disguise yourself as a Mamool Ja.
While in the costume no monsters will aggro you, but the costume wears off when you open a coffer.
The Mamool costume inflicts a heavy DoT effect (30 dmg/tick) and slightly lowers running speed.
Stoneskin, Regen, and Paeon can soften the poison effect in order to keep the costume on longer.
Equipping the Pitchfork +1 event item may not boost movement speed while wearing the Mamool Ja costume, as the status effect granted is "Illusion" and not "Costume".
If you are seen by the Mamool Ja Trainers they will automatically teleport you to a "prison" on the east side of the map next to the Viscous Liquid. If you were carrying any supplies, they will be removed and placed back in the coffer(s) they were obtained from.
Mamool Ja Trainers below bridges can see PCs running across bridges if they take the costume off. Keep the costume on until you reach a chest or are certain there are no trainers along the way.
Mamool Ja Trainers can be killed by high tier elemental magic by level 99 mages or DoT effects such as from Helix spells. If killed in one shot, you will not be sent to the prison. Mamool Ja Trainers respawn in about ~5 minutes. (Mamool Ja Trainers have less than 5k HP)
Mamool Ja Recruits can also be slept or lullabied, and will lose aggro if you are far enough away when they wake.
If you have an item, you can just try to outrun them to the NPC. If you beat them to the NPC and talk to the NPC, the NPC will take your item and the Mamool Ja will deaggro.
Five of the eight chests can only be reached from the prison. The other three can be reached from the start point, but are usually best collected on the way back to the NPC from one of the other chests.
NE corner, up the ramp to the east of the NPC tunnel.
Best collected on the way back from grabbing #3 or #8.
You can also get it from the starting position: Exit out of the tunnel and break left. You'll eventually see a ramp to your left. Go up and follow the path around to the chest. You can go back to the NPC with no problem by traveling back on the top floor and dropping down to the entrance of the starting area. Be sure not to get too close to the ledge if there are mages running around the area, they can see and teleport you from down below.
On the eastern island. Must start from the "Prison".
Get caught by a trainer, use the Mamool costume and head to H-8 by making a right from the costume room. Head north across a bridge to an island with a chest.
After getting this, you can drop down to the west to hit Chest #2.
Under a bridge on the western wall. Must start from the "Prison".
From Chest #4, go west across the bridge and then follow the wall around to the north. Just before the wall turns to the east there is a chest hiding below a small bridge. You can drop down to pick it up or just grab it from on top of the bridge, then continue along the raised platform.
The far south chest. Most convenient to start from the "Prison".
Don't bother with the costume for this one.
From the Prison, head around to H-8 and then follow the left wall and drop down to the tunnel opening where the chest is.
Once you get the chest I suggest going to the right after you exit the tunnel and make your way around back to the exit. There were less mamool wandering around that area.
On a ledge in the SE corner. Must start from the "Prison".
You need to pass one Mamool Ja Trainer to get to this chest. Either you can use the costume, bring another player as a distraction, or just run past while its back is turned.
From the Prison, follow the right wall around to H-8. Avoid the mage there and continue to the right. Shortly after making a right you should see a chest below you on a ledge. Drop off the bridge to reach it.
Try to grab Chest #1 on your way back to the NPC.
The number of items you deliver to Quheeja determines your reward. The minimum number of items to win is two. If you are soloing this, you can win with one item turned in. Once you get the "give up" option at the NPC, choose to spawn the Rune of Release, and receive your rewards. You cannot turn in any additional items after choosing "give up."
Notes[]
It is possible to complete this assault by returning only two items if you have three people.
You must speak to the NPC without any items to turn in and she will give you the option to end the Assault.
Mamool Ja Trainers (and Recruits?) seem to have a much wider angle of vision than average monsters.
The Mamool Ja spend far less time in a stationary position than average monsters. They are very restless and change directions and position frequently.
The chests can be divided into three groups:
The four along the bridge path (#3-#6)
The other two you get starting from the prison (#7, #8)
The two you get on the way back from picking up another one (#1, #2)
So if nobody gets caught you should be able to get all the chests in 6 trips
In a party of three, that means two trips each, first #4-#6, then #3/#7/#8 (for example).
Pick up #1 and #2 as convenient.
If you have a Bard, have everyone gather at the prison first for TroubadourPaeon to go for #3-6.
RDM/THF is good for making the run to #6, with Stoneskin, Regen and Flee.
/SCH is great for this as they can cast Regen II.
THF/WHM or NIN/WHM are excellent job choices for this mission.
One person can grab #3, #2 and #1 in a single trip pretty quickly.
Begin the dialogue with the NPC to exit the assault with no less than 40 seconds remaining. It takes a while for the NPC to talk and unlock the rune, and then for you to access the exit option. It is too easy to try and wait for that one more item that's on its way and time out because of the NPC dialogue. Have a party member at the NPC and ready to exit with 1 minute remaining. If you push it to where only 30 seconds are remaining, you may likely walk away disappointed with a timed-out loss.
Sprinter's Shoes are great for this mission. The effect is not erased when caught by the Mamool Ja Trainers and sent to prison (although it can still be removed by being attacked by the Mamool Ja Recruits). Stack this with any other +movement speed gear (like Strider Boots/Trotter Boots, Ninja Kyahan, Crimson Cuisses, etc..) and it largely overcomes the -movement speed effect from the mamool costume. This will dramatically increase the distance you can cover while in costume. Now add Regen and Stoneskin, and this is a winning combination.
