Hello Ownedcore, first, I apologize if this was already posted, I looked for something about it, but I didn't found anything. Farming low level dungeon became interesting with Xmog, bug sometime you only want the green item, and you waste some time to loot the other body to farm your items. I'm not sure if it's a real exploit, but I can save you some time :
1/ You need 2 players (you and another one)
2/ One of the two player have to pass roll on the loot (not sure if it's the good word, but it's under the option that let you choose lootmaster and other things)
3/ The one who pass roll will be able to see and loot any corpse who have any green item
4/ The other one will be able to roll on them.
I'm sorry if it was posted, and for my bad english. Hope this will be helpful, Ryu.
