One of the few things you should look out for while building your character in Diablo 4, other than the obvious damage output capabilities, is how much your character will be able to handle damage and increase its survivability. Whether your character class is naturally prone to survive enemy attacks like the Druids or Barbarians, or a class that needs skills and passives to ensure you make it out of endgame encounters alive like the Sorcerers or Rogues, making sure you don't fall to your death is a priority and should not be left unchecked.
