'''Faster Run/Walk''' speed, mostly called simply '''FRW''', is a property boosted by equipment (usually [[boot]]s) and also by charms. Heavier [[armor]] and [[shield]]s lowers running walk/run speed and may also increase , while heavier [[Body Armor|body armor]] increases stamina drain.
Faster Run/Walk items will make your character move faster both when Running walking and Walkingrunning. How fast your character actually moves is affected by several factors.
==Background==
All characters in {{iw|Diablo_II Diablo II}} move at the same speed in basic gear, but they differ as they gain bonuses from equipment and skills. Numerous skills increase walk/run/walk speed.
::Unlike attack speed or cast rate, the result of the formula is in YARDS, not FRAMES. All of the frame-based formulas have breakpoints because frames has to be a whole number (i.e. an animation can take 2 frames, or 3 frames, but it can't take 2.37 frames). There is no requirement for *YARDS* to be a whole number (i.e. you can run at 2.37 yards per second), so the formula results in no breakpoints. It's sort of like the [[Magic Find]] formula- both suffer from diminishing returns, but neither has any breakpoints. Every percentage of FR/W and Magic Find is an improvement over the percentage before. -- [http://forumsdiablo.diiiincgamers.netcom/forums/showthread.php?t536403-faster-run-walk-breakpoint&p=536403 5262623&viewfull=1#post5262623 Source]
==Definition of Yards==
Movement speed in Diablo II is measured in yards per second (yards/s). A yard is 48 32 pixels in horizontal direction and 24 16 pixels in vertical direction.
==Visible Screen Size in Yards==
The screen size is 640x480 or 800x600 pixels. The lower panel takes 48 pixels, leaving 640x432 pixels in the smaller screen mode and 800x552 pixels in the larger one for the game play area. Thus, the visible screen has the following proportions in yards:
{|
| 640 x 480
| 640 x 432
| 13.3 20 yards| 18 27 yards
|-
| 800 x 600
| 800 x 552
| 16.7 25 yards| 23 34.5 yards
|}
==Basic Movement Speeds==
The basic walking and running speeds are the same for all characters.
{|
|-
| Walking
| 4 6 yards/s
| -
|-
| Running
| 6 9 yards/s| Walking speed +2 3 yards/s.
|-
| Charging
| 9 22.5 yards/s
| Paladin combat skill. Unaffected by item based Faster Run/Walk.
|}
Monsters' base movement speeds vary.
===Minimum Movement Speed===
Movement speed is affected by items, skills, armor/shield weight, and slowing effects, such as chill and slow.
===Faster Run/Walk: Items===
Walking and running speed are modified by Faster Run/Walk (FRW) items, but charging speed is unaffected by them. Item based FRW is subject to diminishing returns. The effect of 0 % to 295 % FRW to run/walk speed is listed in the table below.

===FRW Diminshing Returns Chart===
Visual representations of this property and its diminishing returns at higher levels. Chart by Virtuous.
[[Image:Frw1.jpg|thumb|600px|center|Faster Run/Walk diminishing returns.]]
Skills, such as Vigor, increase movement speed. Their effect is not subject to diminishing returns. FRW from skills increases movement speed as follows:
{|
|-
| 1 %
| +0.04 06 yards/s
| +0.09 yards/s
|-
| 10 %
| +0.40 60 yards/s
| +0.90 yards/s
|-
| 100 %
| +46.00 yards/s
| +9.00 yards/s
|}
For example, level 7 Vigor gives 32 % FRW, which translates into +1.28 92 yards/s with run/walk and +2.88 yards/s with Charge. FRW from different skills stacks.
===Speed Reduction from Armors and Shields===
Heavy and medium armors and shields reduce movement speed as follows:
{|
|-
| Medium armor
| -0.20 30 yards/s
| -0.45 yards/s
|-
| Medium shield
| -0.20 30 yards/s
| -0.45 yards/s
|-
| Heavy armor
| -0.40 60 yards/s
| -0.90 yards/s
|-
| Heavy shield
| -0.40 60 yards/s
| -0.90 yards/s
|}
Thus, the maximum run/walk speed reduction from the armor and the shield is 01.80 20 yards/s (both heavy). The maximum reduction to charging speed is 1.80 yards/s.
===Slowing Auras, Items & Chilling Attacks===
Anything that slows, such as Slows Target By X% items, [[Holy Freeze]], and [[chill]] from [[cold]] attacks, are treated as negative skill based FRW.
{|
| Chill from a cold attack
| -50 %
| -23.00 yards/s
| -4.50 yards/s
| -50% effect only applies only to players. Monsters have their own valuesplayer, mercenary and pet; monster chill effectiveness varies.

|-

where
* BaseWalkSpeed is 4 6 yards/s for all characters
* Skill_FRW is skill based FRW minus slow effects
* Item_FRW is item based FRW
* Armor_Speed is the sum of the speed reduction from armor and shield (a negative number). The reduction is -5 for medium armors/shields and -10 for heavy armor/shields.
Additionally, if EffectiveWalkSpeed < BaseWalkSpeed / 4, EffectiveWalkSpeed = BaseWalkSpeed / 4. Thus, there is a minimum cap of 1 .5 yard/s for EffectiveWalkSpeed.
===Running Speed===
<blockquote>EffectiveRunSpeed = BaseRunSpeed + BaseWalkSpeed * (Skill_FRW / 100 + [Item_FRW * 150 / (Item_FRW + 150)] / 100 + Armor_Speed / 100)</blockquote>
where BaseRunSpeed is 6 9 yards/s for all characters and other terms as above. Substituting EffectiveWalkSpeed into this formula, we get:
<blockquote>EffectiveRunSpeed = EffectiveWalkSpeed + BaseRunSpeed - BaseWalkSpeed</blockquote>
By entering the values of BaseRunSpeed and BaseWalkSpeed in the formula, we get:
<blockquote>EffectiveRunSpeed = EffectiveWalkSpeed + 2 3 yards/s (where EffectiveWalkSpeed > 1.5)</blockquote> Additionally, if EffectiveRunSpeed < BaseWalkSpeed / 4, EffectiveRunSpeed = BaseWalkSpeed / 4. Thus, there is a minimum cap of 1.5 yard/s for EffectiveRunSpeed.
===Charging Speed===
<blockquote>ChargeSpeed = BaseRunSpeed * (1 + Skill_FRW / 100 + Armor_Speed / 100) + (BaseRunSpeed * 150%)</blockquote>
where the terms are as above. By substituting BaseRunSpeed, we get:
<blockquote>ChargeSpeed = BaseRunSpeed 13.5 yards/s + 9 * (1 + Skill_FRW / 100 + Armor_Speed / 100) * 150%</blockquote>
<blockquote>ChargeSpeed = max(9 yards/s + 6 * (1 + Skill_FRW / 100 + Armor_Speed / 100) , 1.5)</blockquote>
