I know the feeling, trying to get that skill point is hard.
You need to complete the event and that is just very hard to do. From the moment you finish one of the 3 subevents, you need a whole group to defend that part. So you need at least 3-4 groups (probably more) just to finish those 3 subevents. After that, it is a mystery what you have to do. Can’t find enough people to do this event and it is the last thing I need for world completion
Move that skill outside that protective field and it is possible.
