Walking and Running

Player characters may either walk or run, standard key to toggle between the two modes is 'r'. Base velocity values are defined in CharStats.txt and are the same to all classes, say 6 while walking and 9 while running. Some non-player units also use both modi, depending on individual AI. Necessary parameters are defined in MonStats.txt. Note that some units will graphically use both modi, but with the same velocity. Movement speed is subject to a variety of influences.

• some skills grant a bonus
  • - Assassin's Burst of Speed
  • - Barbarian's Increased Speed
  • - Barbarian's Frenzy (some monsters have 'Frenzy' skills of their own)
  • - Druid's Werewolf shape
  • - Paladin's Vigor
• some items grant bonus to Faster Walk and Run (FW/R aka FRW), see Atair's german d2wissen *
• certain armor will bring a penalty if worn; see Appendix' table *
• some effects will slow down an enemy

* This also affects any unit which wears an armor.

Movement mode doesn't affect skills which include character's movement in their attack cycle. This applies to Barbarian's Whirlwind, Leap and Leap Attack as well as to Paladin's Charge. Sorceress' Teleport is also no subject to movement mode.
Attacking and Casting animations won't be affected by movement speed or mode, too.

As long as you actually run your defense is ignored completely, each enemy attack will have a 100% Chance to Hit. Your shield blocking ability is cut down to a third.
Movement speed is enhanceable via some skills and certain equipment, but can also be decreased by foeish curses or slowing effects.
Also armor and shield weights will slow you down. Armors' classification is the same one already known with stamina drain. But stamina does not affect movement speed in any way.

Formula

Run_TU/s = eFRW + [(V_run * 100)/V_walk] + (1+ (FRW_skill+Slow)/100%) - 100 - ∑Armor_speed mit eFRW = [(150 * FRW_item) / (150 + FRW_item)]

Run: movement speed, lower Limit at 15 TU/s: Tile Units per second (1TU ≈ 2/3yard) V_run: velocity from CharStats.txt, run from MonStats.txt respectively V_walk walk from CharStats.txt, velocity from MonStats.txt respectively Slow: slowing effects (Cold has -50% for players) FRW_skill: movement bonus granted by skills FRW_item: movement bonus granted by items eFRW: effective movement bonus granted by items Armor_speed: from Armor.txt [ ]: Floor Function

Charge velocity

Paladin's Charge attack grants a straight bonus of 150% to walking speed, movement mode is automatically set to 'run' while charging (and, if in walking mode befrore, will reset it after the attack). This value is defined in Skills.txt as velocity increase. Running speed while charging is not affected by item boni.

Run_Charge = V_run * (1 + FRW_skill+Slow+Armor_speed) * 150%

% are skipped at both sides of formula

Frenzy

Another example with consideration of Skills.txt entries. Barbarian's Frenzy attack grants a movement speed bonus depending on skill level. This is controlled via a dm34 function, which means Parameter3 as X and Parameter4 as Y are substituted in following formula:

dmXY = { (Y - X) * [110*sLvl / (sLvl + 6)] / 100 } + X thus for Frenzy dm34 = { (200 - 20) * [110*sLvl / (sLvl + 6)] / 100 } + 20

sLvl: actual skill level [ ]: Floor Function { }: Ceiling Function

More about handling of formulas in configuration data is found at Xeno's and kingpin's Formula Guide over at the Phrozen Keep. For common players maybe the existing calculators are good enough, though.

Amazon's Evasive skills

Amazon's Evasive skills Dodge, Avoid and Evade will need eight frames per animation. They seem to be accelerated by skills granting attack speed bonus, thus in unmodified game a friendly Fanaticism aura only (also Assassin's Burst of Speed, if it would be available to Zons).

Some links are quite old and discuss 1.09. But 1.1x didn't change general mechanisms, just the monsters' values were increased.
