We won this Assault today with 4 people scouting the area for the coffers.
Make sure to have every player sub /thf because you need to get to the coffers dispersed around the map before the Mamool Ja find them. Once you open the coffer, a type of Gem will be placed in your inventory and you must bring it back to your start NPC immediately which is located in the southern portion of the map.
Make sure to keep a distance from any Mamool Ja while you have a gem in your possession. If you run into one, they will steel it from you and warp you to the Start NPC.
On the flip side, you are also able to steel gems from Mamool Jas who are also carrying the items back to their treasure NPC.
Only 1 Gem submitted to your Start NPC ensures a successful assault, however the more gems submitted equals more assault points awarded in the end. You must speak with the Start NPC to end the mission as well. We learned the hard way and did not speak to the NPC to end the mission, and failed our first time, even though we had handed in a couple gems. Good luck everyone.
