I know, there are about 4 threads about getting under here.
First thread, requires vehicle..
Second thread, also requires vehicle..
Third thread, requires a disconnect..
Fourth thread, requires a potion.
This thread, requires a slowfall only - even Noggenfogger should cut the time.
1. Head over to this building on your flying mount. You can fly straight through the building.
2. Go through the little crack down into the water.
3. Follow the red line
4. Go to the middle and make sure you are lined up.
5. Open your map, and line yourself up with the left of the building shown in the picture.
6. Swim forwards, jump and slowfall.
7. ???
8. Profit
Under here you can watch the Green and Gold NPCs team battle it out to death, then cheer at each other for their victory.
Have fun!
