League of Legends Movement Speed

What is Movement Speed?

Movement speed is a champion statistic that tells you at what rate a champion travels across a map. Each champion starts the game with base movement speed, ranging from 325 ( Anivia's, Ashe's, Nautilus' and so on) to 355 ( Master Yi's and Pantheon) units per second.

This base movement speed can be increased by flat bonuses and percentage bonuses and reduced by slows. These effects can come from items, champion abilities, spells, masteries, runes or neutral buffs.This base movement speed can be decreased ( Slow ) by certain champion abilities or items; this hindrance is commonly referred to as CC .


How does Movement Speed Work?

Q: How do movement modifiers work?

A: First, you have your base movement of say 325 and you buy Level 2 Boots. That's 370 movement. Then, you get 35% movement speed buff from items, runes or masteries: that 370 is multiplied by 1.35, which results in a total of 499.5 movement speed. If this is the only thing affecting your movement speed, the diminishing returns formula kicks in.

Now, let's say you get slowed by 35% ( Frost Shot). What happens is your movement speed of 499.5 is multiplied by .65, and you are left with 324.67 movement speed. Because 325 is not above or below diminishing returns, you stay at that speed.


Q: What are these diminishing movement returns?

A: Any movement speed bonuses that would cause a champion's movement speed to exceed 415 are reduced by 20%. Any movement speed bonuses that would cause a champion's movement speed to exceed 490 are reduced by 50%.

Above 415: (MS-415) *0.8 + 415 = total MS

Above 490: (MS-490) *0.5 + 475 = total MS


Increasing Flat Movement Speed

Purchasing boots from the store gives a champion a flat increase in movement speed. The effect given by boots is called Enhanced Movement. Enhanced Movement is unique, which means that if a champion was to buy multiple pairs of boots, they will only recieve the highest Enhanced Movement bonus.

Some Abilities that Affect Movement Speed

Strut passively grants Miss Fortune 25 flat movement speed after not taking any damage for 7 or more seconds, increasing by 4 each second up to 70 flat movement speed.

Insanity Potion grants Singed 35 / 50 / 65 flat movement speed for 25 seconds.

Fleet of Foot grants Sivir 30/35/40/45/50 flat movement speed for 2 seconds whenever she hits an enemy champion with Boomerang Blade, Ricochet or for landing a basic attack.

ACTIVE: Sona gains 13 / 14 / 15 / 16 / 17% (+ 2 / 4 / 6%) (+ 7.5% per 100 AP) movement speed that decays down to the aura bonus over 3 seconds. The movement speed bonus is increased by an additional 2% for each rank in Crescendo.

AURA: Allied champions tagged with Song of Celerity's aura gain 10 / 11 / 12 / 13 / 14% (+ 2 / 4 / 6%) (+ 3.5% per 100 AP) movement speed for 1.5 seconds. The movement speed bonus is increased by an additional 2% for each rank in Crescendo.

Night Hunter passively grants Vayne 30 flat movement speed when moving towards an enemy champion. The activation of Final Hour grants her 90 flat movement speed for 8 / 10 / 12 seconds when moving towards an enemy champion instead.


Summoner Spells

Your champion ignores unit collision and has 27% (+1% per champion level) increased Movement Speed for 10 seconds. The movement speed bonus ramps up over the first two seconds.
Heals the caster and the allied champion nearest to the caster's cursor (or the most wounded ally if no target is near the cursor) by 90-345 health, and gives affected champions +30% movement speed for 1 seconds.

Heal is 50% less effective on allies previously healed with another Summoner Spell Heal within the past 35 seconds.

Because the first reduction kicks in as well, so you only get 80% of the boost from 415 to 490, so in the end you get

415 + (490-415)*0.8 + (MS-490) *0.5

Quoted:
Above 490: (MS-490) *0.5 + 475 = total MS

Wouldn't the formula be :
Above 490: (MS-490) *0.5 + 490 = total MS ?
If not, can someone explain me why ?

Sure would, but the chapter says "Some Abilities that Affect Movement Speed" not "All Abilities" :)

Wouldn't Teemo's "Move Quick" and Master Yi's "Highlander" also be applied to this list?
