Death or Glory rule, thoughts?
Saw this video about a rule called Death or Glory for 5e. When reduced to 0 HP you can immediately declare "Death or Glory". You immediately start rolling Death saves until you get either 3 successes or 3 failures. If you get 3 successes first you regain consciousness with 1 HP and when next turn comes up you can take it normally. If you get 3 failures first, you die, pretty simple.
I kind of like it, but think I would limit it to maybe once per long or short rest.
