CDR in League of Legends: Meaning and Usage Explained

TLDR:

CDR stands for “Cooldown Reduction” in League of Legends. It refers to a stat that reduces the amount of time a champion’s abilities take to become available after use. The more CDR a champion has, the more often they can use their abilities, which can be a significant advantage during fights and battles.

If you’re a League of Legends player, you’ve probably come across the term CDR at some point. CDR stands for Cooldown Reduction, which is a stat that affects the amount of time it takes for a champion’s abilities to become available after they’ve been used. CDR is an essential stat for many champions, as it allows them to use their abilities more frequently, which can be a significant advantage in fights.

Previously, CDR was capped at 40%, meaning that no matter how much CDR a champion had, they couldn’t reduce their cooldowns by more than 40%. However, with the introduction of Ability Haste, the cap has been removed, and champions can now stack as much CDR as they want. This change has had a significant impact on the game, as it has opened up new build options and playstyles for many champions.

What Does CDR Mean in League of Legends?

CDR stands for Cooldown Reduction, and it is a stat that reduces the time in which you can use each of your abilities. In other words, it reduces the cooldown of your champion’s abilities, allowing you to use them more frequently.

Cooldown reduction is a fundamental stat in League of Legends that has been around for a long time. It is a valuable stat for champions that rely on their abilities to deal damage, heal, or support their team. CDR can be obtained through various means, including items, runes, and buffs.

It is important to note that CDR does not affect static cooldowns or on-target cooldowns unless otherwise stated. For example, if an ability has a static cooldown of 10 seconds, CDR will not reduce it. However, if an ability has a cooldown of 10 seconds that is reduced by 20% CDR, the new cooldown will be 8 seconds.

CDR can be a game-changer in League of Legends. It allows you to use your abilities more frequently, which can give you an advantage over your opponents. It can also help you to escape from sticky situations or turn the tide of a team fight.

Examples of Cdr Being Used in a Sentence

Here are a few examples of how CDR is used in a sentence:

  • “This item gives 20% CDR, which will significantly reduce the cooldown of your ultimate ability.”
  • “If you build CDR early on, you’ll be able to use your abilities more frequently and gain an advantage over your opponent.”
  • “The champion’s kit has a lot of CDR built into it, allowing them to spam their abilities in team fights.”

As you can see, CDR is often used in the context of item builds, strategy, and champion abilities. Understanding CDR can help you make better decisions during gameplay, such as when to engage in team fights or when to use your abilities to secure a kill.

It’s worth noting that CDR has a cap of 40%, meaning that you cannot reduce your ability cooldowns by more than 40%. However, some champions have abilities or passives that can exceed this cap, allowing for even more frequent ability usage.

First Mention of “CDR” On Reddit

Reddit is a pretty good way to hunt down the early usage of a term, due to it’s large userbase and the fact that it’s been around since 2005.

The first ever mention of “CDR” on Reddit was on Friday 23rd April 2010, by user ‘Narmakaut’, in the /r/leagueoflegends subreddit. The context of the comment is:

I like AP with a dash of CDR builds personally, you’re really squishy but your entire team will be healed for about 1200-1300hp every 45 seconds at endgame. Zhonya’s, Rylai’s, Deathfire, Archangel’s, and Abyssal Scepter should give you a lot of AP.”

Why is CDR important?

In League of Legends, CDR (Cooldown Reduction) is an essential stat that allows you to reduce the cooldown periods of your champion’s abilities. CDR is important because it allows you to use your abilities more frequently, which can be the difference between winning and losing a fight. In this section, we will discuss why CDR is important and how you can optimize your build to maximize your CDR.

Build Options

There are several ways to build CDR into your champion’s kit. Items like Black Cleaver, Ionian Boots of Lucidity, and Luden’s Tempest all provide CDR. Runes Cosmic Insight also provide CDR. By building items and runes that provide CDR, you can maximize your champion’s potential and use their abilities more frequently.

Multiplicative vs. Additive Scaling

CDR can be scaled in two ways: multiplicative and additive. Multiplicative scaling means that the more CDR you have, the more effective each additional point of CDR becomes. Additive scaling means that each point of CDR provides a fixed reduction in cooldown time. In general, items and runes that provide CDR use multiplicative scaling, while champion abilities that provide CDR use additive scaling.

Uncapped CDR

CDR used to be capped at 40%, but with the introduction of Ability Haste, there is no longer a cap on CDR. This means that you can uncap the stat and reach up to 200 Ability Haste, which is equivalent to 100% CDR. However, keep in mind that the effectiveness of CDR diminishes as you approach this cap, so it may not always be the best option to stack CDR to the maximum.

Conversion Guide

If you’re used to thinking in terms of CDR, it can be difficult to transition to Ability Haste. Here’s a quick conversion guide to help you make the switch:

CDRAbility Haste
10%11 AH
20%25 AH
30%42 AH

By understanding the importance of CDR and how to optimize your build to maximize it, you can become a more effective player and dominate your opponents on the Rift.

How to Get CDR

If you want to reduce the cooldown of your abilities in League of Legends, you need to get some CDR. There are several ways to do this, including items, runes, and buffs.

Items

Many items in League of Legends provide CDR. These items are usually designed for mages or supports, but some other champions can also benefit from them. Here are some examples:

ItemCDR
Ionian Boots of Lucidity15%
Archangel’s Staff20%
Shurelya’s Battlesong20%

Runes

Runes are another way to get CDR in League of Legends. The Cosmic Insight rune is particularly useful, as it provides 18 summoner spell haste and 10 item haste.

  • Transcendence: Converts excess CDR into bonus adaptive damage.
  • Absolute Focus: Provides bonus AP or AD when above 70% health.

Buffs

Finally, there are some buffs in League of Legends that can provide CDR. For example, the blue buff in the jungle provides 10 ability haste. Some champions also have abilities that can provide CDR, such as Lux’s Illumination passive or Ezreal’s Mystic Shot ability.

Terms Similar to CDR in League of Legends

CDR is a widely used term in League of Legends, but it is not the only term that refers to reducing the cooldown of champion abilities. Here are some other terms that you may come across:

  • Ability Haste: A new stat introduced in the 2021 preseason that reduces the cooldown of champion abilities. It is similar to CDR, but stacks additively instead of multiplicatively.
  • Cooldown Reduction: The original term used to describe the reduction of the cooldown of champion abilities. It is still used interchangeably with CDR by some players.
  • Reduced Cooldown: Some items and abilities may use this term instead of CDR or cooldown reduction to describe their effect.
  • Cooldown: The amount of time that must pass before a champion can use an ability again. CDR and other similar terms aim to reduce this time.

It is important to note that while these terms may have slightly different meanings, they all refer to the same basic concept of reducing the time that a champion must wait before using an ability again. Understanding these terms can help you make informed decisions when choosing items and runes for your champion.

Conclusion

Understanding CDR in League of Legends is crucial for any player looking to improve their gameplay. Knowing how to maximize CDR can be the difference between winning and losing a game.

It’s important to note that CDR is not the only important stat in League of Legends. Other stats such as attack damage, ability power, and critical strike chance can also greatly impact gameplay.
