How do you get visitor equipment

I've seen people walking around with helmet and armor so i assume there's a way to get it.

Nexon activated stage 2 early, and then had an emergency sc to deactivate it. The people who have the armor got it during the short time stage 2 was active.

There was briefly. Nexon accidentally activated stage 2 of the event, but then canceled it with an emergency server maintenance. The rest of us will just have to wait until they activate it again.
