'''Bullet Lifesteal''' is a stat that causes a percentage of bullet damage dealt to be regained as health.

== Math ==
Despite being presented in-game as +X% Bullet Lifesteal, multiple sources of bullet lifesteal stack multiplicatively, not additively. 

The formula for bullet lifesteal is: <math>BL_f = 1 - \prod_{i=1}^n (1 - BL_i)</math><br/><!--this is rounded, but the game displays two different calculations where one is rounded up, and the other is rounded down--> 
where:<br/>
<math>
\begin{align}
  n &= \text{number of bullet lifesteal sources,} \\
  BL_i &= \text{initial bullet lifesteal,} \\
  BL_f &= \text{final bullet lifesteal}
\end{align}
</math>

For example, with 10% Bullet Lifesteal from [[Crippling Headshot]] and 35% Bullet Lifesteal from [[Leech]], total bullet lifesteal is:

<math>BL_f = 1 - (1 - 0.10) \times (1 - 0.35) = 41.5% \approx 41%</math><!--the stat ingame says 42%, but the calculation on hover says 41%-->
