Found a little bug today when i was doing my quest "Scare the Guano Out of Them!" out in Howling Fjord. I found it annoying that everyone is camping the area and killing the same mobs. Therefore i found a sweetspot to just camp there to gather my 15 Darkclaw Guano required for the quest. You do not have to kill the bat nor will it attack you.
Here is how:
1. Get to the stone at around 31.50,19.9
2. Use the Feknut's Firecrackers and target it at the crack on the stone [Look at image1]
3. When the bat flies down, just back up a few. Next thing you know the bat is stuck at the crack on the stone. [image2]
4. Sit and wait for about 7sec and the bat will head back to its original location.
Good luck to those of you levelling
