Spirit Lifesteal

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

Spirit Lifesteal is a stat that causes a percentage of spirit damage dealt to be gained as health.

Math

Despite being presented in-game as +X% Spirit Lifesteal, different sources of spirit lifesteal stack multiplicatively, not additively. With $n$ different sources of spirit lifesteal, final spirit lifesteal $SL_{F}$ is given by:

$SL_{F}=1-\prod _{i=1}^{n}(1-SL_{i})$

where $SL_{i}$ is the spirit lifesteal provided by the $i$th source.

Example

With 10% Spirit Lifesteal from Enduring Spirit and 35% Spirit Lifesteal from Leech, final spirit lifesteal is:

$SL_{F}=1-(1-0.10)\times (1-0.35)=41.5\%$

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