How to defeat Death and its vampires?

It seems no one has created any tutorial videos. Game streams are sometimes broadcast, particularly for the ongoing World Championship. Keep an eye on the announcements.

By the way, Wizards can escape without an army and without a town portal, as long as at least one survives.

That's understandable. I highlighted escaping through the Town Portal because it's only present in the Whirlwinds, just like teleportation without line of sight.
