4) = 240 raw speed, because of the Slow Resist it reduces 400 raw speed to 400 − (1 − 0. Example: 50% Slow Resist reduces a 40% Slow to a 20% Slow. Main article: Slow resistSlow Resist is a statistic that reduces the effectiveness of slows by a percentage. All additional slows are ignored until the higher-valued slow wears off. Only the slow with the highest value is taken into movement speed calculations. Example 2: If the calculated raw speed is 0 before soft caps kick in, it is increased to 0 × 0. 5 + 110.Įxample 1: If the calculated raw speed is 180 before soft caps kick in, it is increased to 180 × 0.
The raw speed between 415 and 490 gets multiplied by 80%.When the raw movement speed is greater than 415, there are two soft caps applied: If the result is over 415 or under 220 movement speed, apply soft caps as described below. Then, if applicable, apply the slow reduction and any special multiplicative bonuses one at a time. Add all additive percentage bonuses together, add 100% to the result, and multiply it with the total flat movement speed. "MS" is an abbreviation for Movement SpeedĪdd any flat bonuses to the champion's base movement speed the total flat movement speed will be the baseline for the percentage bonuses.(Base MS + Flat MS bonuses) × (1 + Sum of all Additive Percent MS bonuses) × (1 - Highest Slow ratio) × Product of (1 + each Multiplicative Movement Speed bonus)
These effects can come from items, champion abilities, summoner spells, runes and environmental buffs.Ī champion's movement speed is given by the following formula: This base movement speed can be increased by flat bonuses and percentage bonuses and reduced by slows. For a list of all champions' base movement speed, see base champion statistics. The base amount of movement speed a champion can have ranges from 250 ( Rell while unmounted) to 400 ( Cassiopeia at level 18). The collision radius is different from the radius for getting hit by skillshots.Įach champion begins the game with a base amount of movement speed that ranges from 315 ( Janna) to 355 (e.g. The smaller the collision radius, the easier it is for them for move through units without getting blocked. For example, a champion with 300 movement speed will be able to walk the distance of three Teemos standing hat-to-hat next to one another in one second.Įach champion has a collision radius that determines their ability to path around units and for units to path around them. One point of movement speed translates to one game distance unit traveled per second (as a frame of reference, Teemo's hat is circa 100 units in diameter). Movement speed is a champion statistic that represents the rate at which a champion travels across a map.
