In the super popular game League of Legends, what matters in battle is not just who you're playing as but also how you build your fighter's items. This is especially the case when you're playing the game as Annie, the fire-based mage. One way to make Annie super deadly is by maximizing her Cooldown Reduction. With that in mind, here is our recommended Cooldown Reduction build for Annie.

If you reduce the duration of your spell cooldowns by the maximum of 40 percent, you'll be able to use your spells much more often than usual. Therefore, you'll be a much bigger threat overall.

You should start out with basic boots and some health potions. Eventually, convert the boots to Ionian Boots of Lucidity, which increase your movement speed and provide you with an extra 15 percent Cooldown Reduction.

Also, build out your masteries so you get an extra 5 percent of Cooldown Reduction from them, which, when combined with the boots, gives you 20 percent already. Once there, you're halfway home to maximizing Cooldown Reduction.

After that, here's what you should build:

Deathfire Grasp

By getting this item, you give yourself 10 percent Cooldown Reduction and tons of Ability Power. Plus, the active ability that comes with this item allows you to cut through tough champions as well.

Rabadon's Deathcap

Now that you're already well on your way to maxing out Cooldown Reduction, this is the time to invest in an item that will provide you with the ability to deal heavy damage. Say hello to Rabadon's Deathcap, which gives you 120 Ability Power and increases your Ability Power by 30 percent on top of that. Simply put, this is one of the most powerful items a mage can get in League of Legends.

Void Staff

By now, you and any other mages on your team should be dealing plenty of damage. In fact, the opposing team might try to counter you by building items with heavy magic resistance. That's why you should get Void Staff now, which provides you with 70 Ability Power and 35 percent Magic Penetration. By getting Void Staff, you virtually ensure that no amount of magic resist will prevent you from dealing substantial amounts of damage.

Will of the Ancients

As a fragile mage, you could use some more survivability. This item gives you three benefits: 80 Ability Power, 10 percent Cooldown Reduction and 20 percent Spell Vamp. This means 20 percent of the damage you do with your abilities will be returned to you as health.

Liandry's Torment

We recommend Liandry's Torment here for the same reason. This item gives you 50 Ability Power, an additional 15 Magic Penetration, 300 Health, along with a damage-over-time effect equating to 2 percent of an enemy champion's current health and 4 percent against enemies champions whose movement is impaired. The extra health gives you a bit more survivability. By combining all of these items, you give yourself the maximum amount of Cooldown Reduction possible, 35 percent Magic Penetration, 30 Magic Penetration and enough Ability Power to tear through all but the tankiest champions.
