I was in a Arena mode,and I found the wraith got a issue of abduction.
When it wants to use abduction,the skill is locked which means it keep the posture forever.
At the begin
after 16 sec
I play wraith so I know it was happened on me either.When I be locked by abduction,there was no red line to aim the target anymore.The only way to break this issue is using another skill.
There is another issue when the monster evolving(PC),there is a small chance that you can not left click to upgrade ur skill,you should click right button first and then click the left.I dont know how many people know this trick.
