Face Azeroth’s dangers in WoW Classic’s Hardcore realms and see just how far you can go. You only have one life to live, and the Spirit Healers won’t be there to send you back out into the world of the living when you die. Death is permanent, and once you’ve been bested by the environment (or even other players), you’ll need to dust yourself off and create a new character to try again.
