Movement Slow

Movement Slow is a status effect applied by many items and abilities that slows move speed by a percentage.

Movement Slow cannot reduce a player's speed below 2.0 m/s in-game (or 80 hammer units per second).

Math

Slows from multiple sources are multiplicative with each other. Note that displayed speed in m/s is rounded to the nearest decimal for all numbers under 10 m/s.

The formula for movement slow is: ${\text{Total Slow}}=1-\prod _{i=1}^{n}(1-{\text{Slow}}_{i})$
where ${\text{Slow}}_{i}$ is the percent slow amount.

For example, multiple sources of movement slow:

25% movement slow from Slowing Bullets
25% movement slow from Point Blank results in:

$1-(1-0.25)*(1-0.25)=43.75\%{\text{ movement slow}}$

Movement Slow Resist

Movement Slow Resist is applied after the final slow percentage is calculated.

For example, if the player had Enduring Speed with 40% Movement Slow Resist in the above example of 43.75% slow, actual speed would be only be 26.4% slowed.
