Hey, i searched if there was anything about this and i didnt see it anywhere, its not completely useless, its just something that might help people doing that quest ( i did it on 2 characters so far, and doing it on a 3rd and i noticed something strange )
The quest requires you to grab cocoons from Silkwing Cocoons, those cocoons hatch after some time if you dont kill them fast enough ( i think its a random number of secconds ) Thing is, it clearly says in the quest that if you FAIL to harvest the cocoon, then you can still get the wings from the hatched silkwing...
Well, here's the bug. If you let it hatch, and spam click on the cocoon when its hatching, you can loot the cocoon, kill the silkwing and loot the wings... ( it shouldnt let you loot the cocoon normaly )
Its not a huge exploit, just a time saver, knowing that this quest can be a pain for some people, especially with the droprate. Let me know if something is unclear or if you have any questions.
