Blood is a resource common to all players, and is a measure of the amount of blood within your body. You can type BLOOD at any time to see how much blood you have. As you are drained of blood, you will find it more difficult to regenerate your health by natural means. Such natural methods of regenerating health include elixirs, racial regeneration, sleeping, and so forth. Abilities that can recover health are unaffected. If you run out of blood completely or are drained of it by some means within the game, then you will die. Your blood will naturally regenerate over time, however sleeping is a much more effective method that will allow you to regain your blood reserves at a much faster rate. Vampires will need to feed in order to regenerate their blood. Ascended duamvi will need to deliver heathens to regenerate theirs.
