Whenever a character's Wound State drops to MORTAL, he has a pretty good chance of dying. But when? In Cyberpunk, each time you are at a MORTAL wound state, you must make a Death Save to avoid dying. To make the Save, roll a 1D10 value lower than your character's Body Type, subtracting the level of Mortality from your base chance to save. Each turn, you must make another death save to see if the character makes it through another turn. On a successful roll, you make it; on a failed roll, you will die at the end of the turn in which the roll was made.
For example, soy Savage has a Body Type of 10 (Very Strong) and takes a Mortal 4 wound. He must roll lower than (10-4)=6 to stay alive. The first turn he rolls a 5. Whew. The next turn, he rolls a 7 and expires. Immediately, his mates start fighting over who gets his boots.
Get the point? Sooner or later, you'll fail a roll and die. The only way out is stabilization.
Stabilization means the patient is no longer losing blood and that his major damage has been contained through use of drugs, battlefield surgery, and/or wound dressing. A stabilized character will no longer be required to make Death saves each turn. Anyone (except the patient himself) can attempt to stabilize a mortally wounded character; it just works better if the physician has had some medical training. A lot better.
A successful stabilization is made by rolling a total of your TECH stat, any Medical Skill and one D10 for a result equal to or higher than the total number of damage points the patient has taken. For example, Savage has taken 20 points of damage, placing him in a Mortal I Wound State. To stabilize him will require a roll of 20 or greater. Once stabilized, the character is no longer in danger of dying unless another wound is taken. At that point, the whole messy business begins again...
The chances of a successful stabilization roll can be increased by the following modifiers, added to your die roll.
