Diablo III: Reaper of Souls

This trophy will be the most fragile trophy on the list. Playing hardcore mode requires you to not die a single time since it results in losing your character permanently. Also note that nothing except for challenge progress carries over from softcore. Remember that you can play on Normal difficulty for this trophy to lower the risk of dying. Shizo has made a little contribution to how you can survive easier on hardcore, you can find the post here. Some classes are easier than others when it comes to surviving. Personally I would recommend a crusader due to the fact that they have an insane amount of escape mobility and lifesavers such as Akkarat's Champion which has a rune that does so you can take fatal damage once then get healed to full. On top of that they also have a passive skill that does the same. Along with Iron skin, which when activated, reduces all incoming damage by 50%.

See Above & Beyond below for more general information on leveling.

Huge thanks to Shizo for the guide.
