If you want to join the group invited in the stream title, look for Silver Pen 1 in Vampir and choose it if available. The title names that server and invites viewers to play together. It does not establish whether the server is currently open or provide instructions for selecting it.
The source describes a release-day stream, but gives no date. Treat the invitation as tied to that stream, not as confirmation of a current event or active group.

This helped me understand strategy much better.
I tried this today and it worked better than my old setup.
Good guide for Vampir players. The strategy part was useful.
I wish I had read this before upgrading the wrong thing.
