Rage Beyond Death

Beginning at 14th level, the divine power that fuels your rage allows you to shrug off fatal blows.

While you're raging, having 0 hit points doesn’t knock you unconscious. You still must make death saving throws, and you suffer the normal effects of taking damage while at 0 hit points. However, if you would die due to failing death saving throws, you don’t die until your rage ends, and you die then only if you still have 0 hit points.
