Hit points
Hit Points (or HP) define the amount of damage your character can take before dying.
When your hit points reach 0 or below, you fall on the ground knocked down, which means you can only whisper. While knocked down you are unable to do anything. When your HP goes to -20 you will die, but if not in combat, your HP will regenerate every 2 minutes allowing your character to stand back up when it reaches 1 or above.
Hit Points regeneration
You can get back your hit points using:
- Hit points regenerate every 2 minutes by amount of Healing Rate
 - A stimpak (+10-40hp), weak healing powder, healing powder (up to +20 hp), or a Super Stimpak - take care about the drugs inconveniences first, though.
 - Your First Aid skill, that will heal you depending on the amount of skill points in the skill, with a cooldown if you use it (With 200% for example, you'll heal your target for up to 200 hit points). The average amount you can heal at a time is based on your Luck. The First Aid skill will award you 3xp for each hit point healed.
 - You can ask Wasteland Doctor to heal you for caps.
 
Maximum Hit Points
The base maximum hit points formula is 55+Strength+(2*Endurance).
Additionally, you will be awarded more hit points when you go up a level. The formula for hit points per level is Endurance/2. As the number of hit points per level is rounded down, it is advised to have an even number of Endurance points (2, 4, 6, 8, 10).
| Endurance | Hit points per level | 
|---|---|
| 1 | 0 | 
| 2 | 1 | 
| 3 | 1 | 
| 4 | 2 | 
| 5 | 2 | 
| 6 | 3 | 
| 7 | 3 | 
| 8 | 4 | 
| 9 | 4 | 
| 10 | 5 | 
Lifegiver bonus
Each lifegiver perk will grant you an added number of hit points. Because you can take it three times, the final bonus can be +90 hit points.
