How do I reach Umbrall Grotto? I tried to run there, but there were rocks in the way (I'm assuming a certain quest needs to be done). Its definetly a part of the sneak peak event, but what do I need to do to get there?
I'm quite sure its in the event because its posted on the map on the official site. The map that dictates places you can go during the event. Plus, I heard of a couple people that go there.
