Dying / Stable Indicator
The Dying / Stable indicator applies an indicator to a PC when they are at 0 HP. NPC entries will immediately show the "dead" indicator, while PC entries will show as Dying, Dead, or Stable depending on their health status. Some icon sets show different dying images based on the number of failed death saving throws.
Dying 0: PC is at 0 HP but no failed death saving throws
Dying 1: PC is at 0 HP with one failed death saving throws
Dying 2: PC is at 0 HP with two failed death saving throws
Stable (5e): A PC is stable if it is at 0HP, and has the "Stable" effect applied to it, or has 3 successful death saving throws.
