Diablo III: Reaper of Souls

For this trophy you will have to kill Malthael in Hardcore mode which I would recommend you do once you feel comfortable enough with your current items before you engage him. See Death Do Us Part for more in-depth info on Malthael. You can always back up your save game incase you should die then simply reload it. Remember that you can always have the difficulty set to Normal to avoid any further trouble, and if you know someone who is a high level in hardcore, they can help out, but still be careful as you can still die easily.
