If the damage is:

>=HP+MaxHP	Dead
>=HP	Unconscious
<HP	Subtract from HP

If you are unconcious, begin making Death Saves.

Death Saves:

Roll d20	Result
1	+2 Failures
2-9	+1 Failure
10-19	+1 Success
20	Regain 1 HP

If you take damage while unconcious, it counts as 1 Failed Save. Any Melee attacks are Critical Hits and count for 2 Failed Saves.

If you fail 3 Death Saves, You Die.

If you succeed 3 Death Saves, You are Stable at 0 Hit Points, after 1d4 hours you recover 1 Hit Point and regain consciousness.
