Yes vv3 i killed alani that way
. i was tottally alone when i used sky crystal !
(im also first on server to get exalted with golden lotus so none to worry about coming and stealing it )
As for the skyshards u are just unlucky. RNG sucks some times..
At first shared it with my mates and 1 of em still cant get his last skyshard.. whilst others got like 3-4 in a couple of hours.. Just keep killing that cow and eventually they will drop :P
