I need to know the max values of the following attributes if there's one:

• critical chance
• attack speed
• run speed
• dodge

Also, does anyone know how the formula for damage received/inflicted?

- Attack speed is capped at 2.5 attacks a second.
- Citical chance stack additively. so even being able to get it past 100% would be a waste so cap is 100% ;]
- run speed is unknown but there is a post with a rammus with speed ball with over 2000ms \o/
- dodge cant get all the way to 100% since it stacks multiplying the dodge chances...but kat with dodge items should get really close to 100%

For damage calculations:

Every 1 armor means the damage it takes to kill you is extended by 1% of your hitpoints. At 100 armor, it takes 100% more damage to kill you, ie it requires double damage, ie you're taking half-damage. At 300 armor you're taking 25% damage, etc.

Magic resistance works in the exact same fashion, except it does so against spells only. There is no overlap between armor and magic resistance at all. (Ex. Having 500 Armor would have no impact on spells, having 500 Magic Resistance would have no impact on physical attacks)

This is all directly from the FAQ stickied at the top of this section

A: The best way to show how dodge works is an example, let's say you have 10% dodge in your runes.

10% dodge.

You grab Ninja Tabi, which gives 11% dodge.

11% dodge +
(89 * .1) = 8.9% dodge

For a total of 19.9% dodge. (Note that the 89 comes from the percent remaining from the previous dodge percentages have been calculated.)

You then get Phantom Dancer, which gives 20% dodge.

20% dodge +
(80 * .11) = 8.8% dodge +
(71.2 * .1) = 7.12% dodge

For a total of 35.92% dodge.

Q: How does armor and magic resistance work? (Credit to Garek for framing it better than I could.)

Q: What order is armor penetration/MR penetration applied in? (Credit to TiberiusAudley)

A: From top to bottom

Armor/MR Reduction
% Based Armor/MR Penetration
Flat/Linear Armor/MR Penetration

Q: Can you reduce armor or magic resistance below 0?

A: Yes, although the only things that can reduce below 0 is Armor/MR Reduction. Both percentage and flat penetration do not have an effect after they get to 0 armor/MR.

Q: Are there any other caps that I should know about?

A: Attack speed is capped at 2.5 attacks a second.

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.
