Movement speed advantage required for a given attack efficiency when chasing

Movement speed (sometimes abbreviated as Move Speed or $ms$ ) is the speed at which a unit can move over a second. The default movement speed caps are at 100 on the low end, and 550 on the high end, which can be bypassed by only a few abilities. Only units capable of moving can have a movement speed. This means granting a non-mobile unit movement speed with an ability does not allow them to move still. A unit's movement speed can be increased by abilities, items or talent. Some items grant passive speed bonuses to the wielder.

Min Move Speed	Max Move Speed
100	550

Commands

There are several different orders which make the unit move.

Move Command

The default move command is bound to Right Click or M, it can also be bound to a Hotkey. Targeting the ground with this command makes the unit move to that point, or until unable to get closer to the point (i.e. target is out of reach). During a move command, the unit does not automatically attack enemies on the way.

Follow Command

The follow command is merged in with the default M move command, and is executed with the same keys. To follow a unit, the move command has to be targeted on the desired unit to follow. Targeting an allied unit with the move command makes the unit follow the allied unit, until a new order is given or until the targeted unit dies. The follow range for most units is 100, meaning a unit ordered to follow another unit attempts to stay within 100 range of the targeted unit. Mobile ward type summons (such as Healing Ward) have a follow range of 250. In order to follow enemy units, the Hotkey must be used, since Right Click on an enemy automatically orders an attack on it.

Patrol Command

The patrol command makes the unit move back and forth between its starting location and the targeted point, until it is given another order. A unit can be given multiple points to patrol. When doing so, the unit moves to the targeted points in the same order in which they were given. Upon reaching the last point, it moves back in reversed order. Just like the move command, the unit does not automatically attack enemies it crosses while patrolling.

The default hotkey for the Patrol Command is <blank>.

Attack-move Command

The default Attack-move command is bound to A, it can also be bound to a Hotkey.

Identical to the move command, with the difference being the ordered unit attacking any enemy they cross while moving. This order can be given by giving an attack order onto the ground. To do this, the attack Hotkey must be used. If the unit crosses no enemies during an attack move order, it essentially acts as a move order. When an enemy gets within the unit's acquisition range, it goes towards that enemy and attacks it. If the target can no longer be attacked for any reason (dies, becomes ethereal or invulnerable, turns invisible or loss of sight over target), the unit resumes moving towards the targeted point, continuing from its current location. It does not trace its way back to where it left the path to attack an enemy.

Total Movement Speed

Calculating the total movement speed of a unit involves using a few values and a multiplier.

• If a Set Movement Speed value is present, the set value overrides the unit's original base movement speed.
  • If the Set Movement Speed value is absolute, the absolute value is now the unit's Total Movement Speed.
  • Absolute Movement Speed can only be affected by haste and abilities that modify minimum movement speed limit.
• Flat movement speed bonuses (items, abilities and talents) are simply added to the base movement speed of the unit.
• Movement speed percentage based bonuses and slows get all summed up, and then applied to the unit's base movement speed as a multiplier.

Movement Speed Multiplier ( ${ms}_{Mu}$ ) is defined as

${ms}_{Mu}=1+\sum _{i=1}^{n}(a_{i}-r_{i})$

With a and r being the positive (bonus) and negative (slows) movement speed percentage values respectively.

Total Movement Speed is defined as

$\sum {ms}={\begin{cases}\mid ms\mid &\quad {\text{if }}\!\!&\mid ms\mid &=\top \\(ms_{B}+ms\sum _{i=1}^{n}f_{i})\times ms_{Mu}&\quad {\text{if }}\!\!&ms_{Set}&=\top \,\rightarrow \,ms_{Set}=ms_{B}\end{cases}}$

With |ms| being the Absolute Movement Speed value, msSet the Set Movement Speed value, msB the Base Movement Speed and msf the Flat Movement Speed values.

Stacking Restrictions

However, most item-based speed bonuses have stacking restrictions. Passive movement speed bonuses from items are separated into groups. The movement speed bonuses of the items in their groups do not stack with each other or with multiple of themselves, but do stack with the bonuses from items from the other groups.

• Group 1: Boots
• Group 2: Yasha based items.
• Group 3: Wind Lace itself.
• Drum of Endurance, Eul's Scepter of Divinity, and Solar Crest are in no group, so they fully stack with each other, with multiple of themselves, and with all other item bonuses, including Wind Lace.
• Bonuses from abilities and talents have no such restrictions and stack with all other bonuses.

Group 1	Group 2	Group 3	No Group
Boots	Yasha based.	Wind Lace only.
Boots of Speed Boots of Travel 1 Boots of Travel 2 Arcane Boots Guardian Greaves Phase Boots Power Treads Tranquil Boots Force Boots	Yasha Sange and Yasha Yasha and Kaya Manta Style	Wind Lace	Eul's Scepter of Divinity Solar Crest Wind Waker Spider Legs

Examples

Example 1

A maxed level Windranger with Windrun has Boots of Travel 2 and Manta Style. She is currently affected by a level 4 Tether. What is her current movement speed?

Flat movement speed values:

• Windranger's base movement speed: 290
• Wind Waker: 50
• Boots of Travel 2: 120

Percentage movement speed values:

• Windrun: 60%
• Manta Style: 8%
• Tether: 12%

${\begin{aligned}\sum {ms}&=(ms_{B}+ms\sum _{i=1}^{n}f_{i})\times {ms}_{Mu}\\&=(290+60+120)\times (1+0.08+0.12+0.6)\\&=828\end{aligned}}$

Windranger has a theoretical movement speed of 828 from abilities and items in this calculation example, but it gets capped at 550, so long she is not affected by anything that unlocks the maximum movement speed.

Example 2

The same Windranger from the previous example is now also affected a level 4 Thunder Clap, along with the level 4 Tether. What is her current movement speed?

Flat movement speed values:

• Windranger's base movement speed: 290
• Wind Waker: 50
• Boots of Travel 2: 120

Percentage movement speed values:

• Windrun: 60%
• Manta Style: 8%
• Tether: 12%
• Thunder Clap: 55%

${\begin{aligned}\sum {ms}&=(ms_{B}+ms\sum _{i=1}^{n}f_{i})\times {ms}_{Mu}\\&=(290+60+120)\times (1+0.08+0.12+0.6+-0.55)\\&=575\end{aligned}}$

Windranger has a theoretical movement speed of 575, which again gets capped at 550. This example shows that the movement speed cap is ignored by the calculations, meaning the strong slow of Thunder Clap is not applied to her actual current movement speed of 550, but gets subtracted from from the percentage-based movement speed bonuses before being applied to the sum of the flat movement speed values.

Base Movement Speed

Every unit capable of moving has a base movement speed ( $ms_{B}$ ) value. This value is fixed, and can only be altered by very few abilities.

Heroes

The following list shows the base movement speed of all heroes, and their movement speeds with any of the items based on Boots of Speed

Set Movement Speed

Set Movement Speed ( $ms_{Set}$ ) sets a unit's movement speed to a fixed value for the duration. The units are still fully affected by flat and percentage-based movement speed changes. The movement speed is still bound to the minimum and maximum movement speed limits. If a unit is affected by multiple abilities in this list, the lowest value takes priority.

The following abilities are able to override a unit's base movement speed, setting it at a certain value.

Set Move Speed Abilities

• Elder Titan - Astral Spirit
  
  Duration: 10
  Sets Astral Spirit's base movement speed equal to the caster's movement speed upon cast.
• Ember Spirit - Fire Remnant
  
  Remnant Travel Speed: 250% ( 500%)
  Fire Remnants move to their targeted location at a speed set upon cast based on the caster's movement speed. The speed does not adapt.
• Io - Tether
  
  Grants the target movement speed bonus while the caster copies the target's movement speed.
• Helm of the Dominator - Dominate
  
  Set Move Speed: 380
  Permanently changes the target unit's base movement speed.
• Lifestealer - Infest
  
  If the target is a creep, periodically sets its base movement speed equal to that of the caster.
• Morphling - Morph
  
  Duration: 20 ( 36)
  Sets the Morphling's base movement speed equal to that of the target.

Hex

Besides disabling, hex also directly sets ( $ms_{Set}$ ) the target's movement speed to a fixed value for the duration. This means hex does not slow the target. Every percentage based movement speed can increase and reduce the target's movement speed as usual. The same applies to hastes, which still have full effect on hexed units.

• Dazzle - Poison Touch
  
  Duration: 1.25
  Animal: Pig
  Set Move Speed: 100

Absolute Movement Speed

The following abilities set a unit's movement speed to an absolute value ( $\mid ms\mid$ ). No other values can change them, with the only exception of abilities that increase the minimum movement speed limit, which includes all Hastes.

Absolute Movement Speed is defined as

$\mid ms\mid ={\begin{cases}\sum {ms}\quad &{\text{if }}&\mid ms\mid &=\top \\{\text{min}}(ms)\quad &{\text{when }}&{\text{min}}(ms)&=\top \\ms_{Haste}\quad &{\text{when }}&ms_{Haste}&=\top \end{cases}}$

Movement Speed Limits

By default, the lower limit for movement speed is at 100, while the upper limit lies at 550. These values are the same for all units and cannot be exceeded by flat or percentage movement speed bonuses or reductions. Base movement speed changes cannot exceed these either.

Minimum Movement Speed

The following abilities are able to change a unit's minimum movement speed, preventing it from ever being lower than the set value. If a unit is affected by multiple abilities that change the minimum value, the higher value takes priority.

Minimum Move Speed Changing Abilities

• Monkey King - Mischief
  
  Set Move Speed (Default): 200
  Set Move Speed (Courier): 380
  Requires Aghanim's Shard, otherwise it sets the caster's movement speed instead.

Maximum Movement Speed

The following abilities are able to change a unit's maximum movement speed (of 550), allowing it to reach even higher values. If a unit is affected by multiple abilities that change the maximum value, the higher value takes priority.

  Completely removes the movement speed limit for the hero once the ability is learned.
• Force Boots - Speed Unlock
  
  Removes the movement speed limit for the wielding unit.
