'''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. 

Despite being presented in-game as +X% Bullet Lifesteal, different sources of bullet lifesteal stack multiplicatively, not additively. With <math>n</math> different sources of bullet lifesteal, final bullet lifesteal is given by:

<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 BL<sub>''i''</sub> is the bullet lifesteal provided by the ''i''th source.

===Example=== 

With 10% Bullet Lifesteal from [[Crippling Headshot]] and 35% Bullet Lifesteal from [[Leech]], final bullet lifesteal is:

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

Note that the in-game user interface is inconsistent in how it rounds the final number.
