This article is about the stat. For the item, see Bullet Lifesteal (item).

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

Stacking

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

$B{L}_{Total}=1-\prod _{i=1}^n(1-B{L}_i)$

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

$B{L}_{Total}=1-(1-0.10)\times (1-0.35)\approx 41\mathrm{\%}$
