Dying

When at 0 HP
Characters that drop below 0 hp dip into negative hp. A character at below 0 hp is considered dying and loses 1 hp at the start of each of their turns. A character who takes damage while bleeding out bleeds for an additional 1HP per round. A character who drops to negative half hp dies immediately. Existing death save rules still apply.

When a character below 0 hp is healed, restore that amount of health; they do not immediately jump to 0 hp. Magical healing or a medicine check with a dc equal to 10 +½ negative hp will stabilize the character, preventing further bleeding and death saving throws.

A stabilized character who is below 0HP and takes damage begins bleeding again and is no longer stabilized.
