League of Legends 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.

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
