Huskers412 wrote Dung Glitch modified version!
So if you know the old patched dung glitch involving teleportation, this is similar but it bypasses the patch!
1)Get 2-5 ppl in your party. 1 of them must have a high dung lvl, 80+ preferred.
2)The account that needs leveling is will be referred to as A, and the high level dunger is B!
3)B will invite everyone to a floor 1 complexity 6 party and everyone must accept, including A.
4)B will then click on dungeon entrance and get to the screen where is asks for the dungeon size.
5)He will wait there while A gets an item in his inventory from bank.
6)A gets the item, and then B click "Large" (or "Medium" if this is only a 2 person party).
7)Of course with the item in A's inventory, it will fail.
8)B kicks everyone from the party including A and changes the complexity to 1.
9)Then B reinvites ONLY A to the party, and A must get to the screen where she would normally accept.

NEW STEP!!!!!! Different from Old Dung Guide!!!!!!
10)The timing of the teleport and accepting must be exactly the same so if there are 2 people doing this together
make sure to come up with some signal or use voice chat!
11)B teleports at EXACTLY or immediately after A clicks "Accept".
12)B teleports constantly without breaks in teleportation while A clicks "Form Party" and makes a f1c1 party alone
and enters the dungeon.
13)B stops teleporting and must get the message "A has entered the party".
14)A then completes dungeon and kills boss, BUT DOESN'T click on the exit ladder.
15)B changes floor and complexity to his max. eg: floor 40 complexity 6. Then exits party himself.
16)A exits via ladder and gets insane xp.
17)Redo at infinitum.

Thanks, + Rep, and Thank the Topic.
