What’s the difference between Ability Haste and CDR in League of Legends?

CDR, or cooldown reduction, is a key statistic in the popular online game League of Legends. It has a significant impact on a player’s ability to succeed in battle, granting them access to powerful abilities more frequently and in a shorter time span. Knowing how to properly manage CDR can give players an edge against their opponents and increase their chances of victory. This blog post will explain what CDR is and how it works, as well as exploring some of the more advanced strategies related to CDR that experienced players can use to gain an advantage. We will also discuss the items and abilities that can be used to increase CDR. Lastly, we’ll take a look at some of the best team compositions that make use of CDR to maximize their chances of success. So join us as we explore the world of CDR and how it can be used to gain the upper hand in League of Legends.

Cooldown Reduction (CDR) was a statistic that reduced the cooldown of champion abilities. It did not affect static cooldowns nor on-target cooldowns, unless it was otherwise stated. Other forms of cooldown reduction existed for items, summoner spells, and specifically ultimate abilities.

Is Ability Haste Better than CDR?

While AH stacks additively, CDR stacks multiplicatively, making each point of CDR more significant than the previous one. That means that as you add ability haste, you will not experience exponential growth. Unfortunately, it turns out that the value of the ability haste decreases as you acquire more of it, as shown below.

As you can see, just like with the cooldown reduction stat, your cooldown decreases as you gain ability haste. Unfortunately, as you can see in the “Percent Change column,” the amount of cooldown you gained compared to the last bit of AH you received is less effective. The amount a skill’s cooldown decreases gets smaller across all three champions and their abilities. Compare this to old CDR.

As you can see, the multiplicative stacking occurs because the amount that an ability’s cooldown decreases increases as you gain more CDR. Additionally, even though the first 10 AH you receive are roughly as effective as the first 10% CDR, they are still slightly inferior. Ability haste is undoubtedly a worse overall stat given that it becomes less potent as you add more.

Thus, the reason for Riot’s change must be asked.

It is evident that ability haste and cooldown reduction are related when changing the change in cooldown reductions to added haste. Check out this conversion guide if you’re having trouble switching from cooldown reduction to ability haste:

  • 10% CDR = 10 AH
  • 20% CDR = Approximately 25 AH
  • 30% CDR = Approximately 40 AH
  • 40% CDR = Approximately 70 AH
  • 50% CDR = 100 AH
  • 60% CDR = 150 AH
  • – Abbreviations: Critical strike chance (CS), attack damage (AD), ability power (AP), attack speed (AS), CD, and gold per 10 seconds , Hp5: health regen per 5 sec. life steal, magic damage, and mana regeneration every five seconds You can sort multiple columns by holding shift and clicking on other column headers., MR stands for magic resist, MS for movement speed, PD for physical damage, and SV for spell vamp. Mejai’s Soulstealer’s bonus CDR corresponds to 20 stacks.

    Fortunately, that’s not always the case. Nashor’s Tooth and Stinger are practically equally cost-effective. Building Nashor’s Tooth for pure CDR is a wise investment, despite the fact that Fiendish Codex is a little less effective. Additionally, Morello’s Evil Tome is a net improvement over Fiendish Codex due to its affordable price.

    In conclusion, Nashor’s Tooth, Morello’s Evil Tome, and Frozen Heart appear to be the most cost-effective items with the highest CDR bonuses. As a result, they are the items that are suggested when shorter ability cooldowns are needed. Nevertheless, a carry won’t find many uses for CDR items aside from Youmuu’s Ghostblade; perhaps.

    All champions gain from having more opportunities to use their abilities. In order to determine which items with a CDR bonus aid in the performance of carries, mages, tanks, and support, an analysis of items that provide CDR will be helpful. By selecting each header in the following table, you can sort the data. The final column displays each item’s cost effectiveness, or the price per CDR unit: 1%. More CDR is obtained for the least amount of gold the more cost-effectively. Let’s see what this uncovers.

    Elixir of Brilliance is a very affordable item to temporarily increase CDR. But when we consider permanent bonuses, Ionian Boots of Lucidity stand out as the most reasonably priced item to increase CDR. Although Mejai’s Soulstealer is also reasonably priced, Ionian Boots are the superior option due to its reliance on stacks.


    Is ability haste the same as CDR?

    Ability Haste is more adaptable and can lead to clearer build choices than Cooldown Reduction, which is how they differ in League of Legends. In the League’s 2021 preseason, Riot said “adieu” to Cooldown Reduction (CDR) and debuted Ability Haste, an updated version of the stat.

    How is cooldown reduction calculated?

    A feature that cuts down on that waiting time by a specific percentage is called cooldown reduction. You might, for instance, possess a weapon with a 10% reduction in cooldown. You will only need to wait 27 seconds, or 3 seconds, or 10% less, after using a skill that has a 30 second cooldown.

    What CDR is 15 ability haste?

    If you only acquire two items with the 15 ability haste, your CDR will be between 20 and 30 percent. However, you can fully spec into maximizing your ability haste if you choose to. It is possible to obtain up to 200 ability haste through items and runes. That is equivalent to about 66. 7% cooldown reduction.

    How much CDR does ability haste give?

    Haste ability has a maximum stack size of 500, which is equal to 83. 3% cooldown reduction).
