### Movement Speed FAQ

III. Movement

Q: How much movement do the different levels of boots add?

Q: How do movement modifiers work? (Credit to Larias)

A: First, you have your base movement of say 300. You add boots first, always boots first, so if you have boots added.

Let's say you get boots 2. That's 370 movement. Then, you get 35% movement speed buff from items or runes or masteries or buffs: that 370 is multiplied by 1.35, or 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 38% (ashe arrows). What happens is the ORIGINAL 499.5 is multiplied by .62, and you get 309.69 movement speed. Because 309 is not above or below diminishing returns, you stay at that speed.

Q: What are these diminishing movement returns? (Credit to Guinsoo)

A: For each point of movement you would have above 490, that amount is reduced by 50%. So if your final movement speed was 748, it would be reduced to 490 + (748-490)*0.5 = 604. For each point of movement you would have above 415, it is reduced by 20%. So if your speed after all mods was 445, you would end with 415 + 30 * 0.8 = 439.

Q: Do slows stack?

A: Sort of. Item slows do not stack - if you have two people with Frozen Mallet, for example, the slows will not stack. This includes two different items as well: if you have a Frozen Mallet and a Rylai's Scepter, the slows will not stack.

Ability slows do stack; however, they do not work additively. If you have two 50% slows, it's not a 75% slow or a 100% slow. There are soft caps on how far you can be slowed (and hasted), and these kick in.

Item slows and ability slows stack. Different ability slows do not stack. According to Veigar, at least =/

I'll update it with Guinsoo's information until I can get it from Veigar.

Slows don't stack but if a 40% slow and a 30% slow are done to a champion at the same time the 40% will stay on for its duration (say its 4seconds) then once that ends the 30% slow will last for one second (assuming the 30% duration is 5 seconds).

Q: How fast is it possible to go?

A: http://www.youtube.com/watch?v=Yms28nEWaTo but not in a normal game.

I recently did a test with EnygmaSoul on how slows work.

The rule worked as thus: The strongest item slow will combine with the strongest ability slow for its total value, and recalculate to lesser potent slows from both ability/item as each falls off. You can apply additional item slows and ability slows, but they will do nothing other than stick and wait for the stronger slows or its own debuff to fade.

In other words, Ashe with Frozen Arrow + Frozen Mallet is an insanely potent slow. And if Nasus were to for whatever reason use Wither, Mallet and Rylai's on his Spirit Fire, only the Wither and Mallet would work as the Rylai's slow would be the weaker value.
