Editing Move SpeedGive feedback

'''Move Speed''' is a stat that [[heroes]] start with and can obtain more through [[items]]. Move speed dictates how many meters per second the hero will move.

''See also: [[Movement Slow]]''

== Overview ==
Heroes will accelerate up to base movement speed velocity from a standstill. Move Speed bonuses from items and abilities stack diminishingly, meaning adding more speed provides progressively less value.

While firing, a hero's movement speed is reduced to 75% of its normal value (a 25% slow), which can be mitigated by {{ItemIcon|Fleetfoot}}. There is no penalty while zooming in. While crouched, all heroes have 4.8 m/s crouch speed not affected by the movement speed penalty, except for {{HeroIcon|Grey Talon}} and {{HeroIcon|Warden}}, whose movement speed penalty while firing applies while crouched, becoming 4.4 m/s. 

Move Speed is an important stat in overall [[movement]], as it affects how quickly one can reach their destination.

Some heroes have [[Spirit Scaling]] affecting their Move Speed and Sprint Speed. See "Base Move and Sprint Speed" table below.

=== Sprint Speed ===
'''Sprint Speed''' is a related stat that is conditionally added to a hero's move speed when a hero is out of combat for five seconds, and persists until entering combat or zooming in. Zooming in while sprinting resets the player's speed back to base move speed.

If the hero has more than '''2.5m/s Sprint Speed,''' the rest of the sprint speed will be added to the hero's movement at a rate of '''0.6m/s''' as the player moves. While capped at the hero's Sprint Speed stat, sprinting will continue building up past its current max value, meaning bonuses applied while sprinting (e.g. [[Healing Rite]]) will instantly increase current Move Speed. Sliding, taking damage, getting [[Crowd Control#Stun|Stunned]], [[Crowd Control#Immobilize|Immobilized]], [[Crowd Control#Displace|Displaced]] or [[Crowd Control#Sleep|Slept]], using a [[Ziplines|Zipline]], or stopping movement input will reset this counter.

=== Slide ===
Heroes moving above 8.9 m/s can slide on a flat horizontal surface by crouching.

== Calculation ==

=== Calculating Move Speed ===
While items often display movement speed bonuses as flat values (e.g., +2 m/s), multiple sources of move speed do not simply add together. Instead, they stack '''multiplicatively''' using a similar formula to [[Damage Resistance|resistance]], meaning each additional source provides diminishing returns.

To find your effective move speed bonus, use the following formula:

<math>\text{Effective Move Bonus} = 12 \times (1 - (1 - \frac{B_1}{12}) \times (1 - \frac{B_2}{12}) \dots)</math>

Where B₁, B₂, etc. are individual move speed bonuses.

Then calculate your total speed:

<math>\text{Total Speed} = \text{Base Move Speed} + \text{Effective Move Bonus} + \text{Base Sprint Speed} + \text{Sprint Bonus}_1 + \text{Sprint Bonus}_2 \dots</math>

'''Example:'''
If you have two sources of move speed, one providing '''+2 m/s''' and another providing '''+3 m/s''':
# Divide each bonus by 12: ≈0.167 and 0.25.
# Subtract from 1: (1 - 0.167) = '''0.833''' and (1 - 0.25) = '''0.75'''.
# Multiply the remainders: 0.833 × 0.75 = '''0.625'''.
# Subtract from 1: 1 - 0.625 = '''0.375'''.
# Multiply by 12: 0.375 × 12 = '''4.5 m/s''' (exact).
# Your Effective Move Bonus is '''4.5 m/s''' (not 5 m/s).

If your hero has 6.5 base move speed, 1.6 base sprint speed, and no sprint bonuses:
<math>6.5 + 4.5 + 1.6 = \mathbf{12.6 \text{ m/s}}</math>

=== Sprint Speed Stacking ===
Unlike move speed, sprint speed stacks '''additively''' with no diminishing returns. If you have base 1.6 sprint speed and get items with +2 and +5 sprint speed, you simply have 8.6 sprint speed.

<math>\text{Total Sprint} = \text{Base Sprint} + \text{Bonus}_1 + \text{Bonus}_2 \dots</math>

=== Combined Example ===
A hero with:
* 6.4 base move speed
* 1.6 base sprint speed  
* +2 and +3 move speed bonuses
* +2 and +1.5 sprint speed bonuses

'''Step 1: Calculate Move Speed'''
<math>12 \times (1 - (1 - \frac{2}{12}) \times (1 - \frac{3}{12})) = 4.5 \text{ m/s effective}</math>
<math>6.4 + 4.5 = \mathbf{10.9 \text{ m/s}}</math>

'''Step 2: Calculate Sprint Speed'''
<math>1.6 + 2 + 1.5 = \mathbf{5.1 \text{ m/s}}</math>

'''Step 3: Add Together'''
<math>10.9 + 5.1 = \mathbf{16.0 \text{ m/s}}</math>

* {{ItemIcon|Frenzy}} additionally increases move speed by +{{#invoke:ItemData|get_prop|Frenzy|FervorMovespeed}}/s while below 50% health.
* {{ItemIcon|Metal Skin}}, when activated, provides -1.5 m/s Move Speed Penalty

=== Map Spawns ===
* [[Powerup]] runes can provide a temporary Movement buff that provides +'''1.5'''m/s to +'''4'''m/s Sprint Speed for 160 seconds (scaling with game time from 5 to 40 minutes).
* After taking a [[teleporter]], there is a temporary move speed buff.
* [[Vent|Vent tunnels]] provide a '''70%''' boost to Move Speed. Sprint Speed is not multiplied by this boost.
