In the super-popular game "League of Legends," what matters in battle is not just who you're playing as, but also how you use and build them. This is especially the case when playing the game as Morgana, the Ability Power-based Mage.

One way you can make Morgana super deadly is by maximizing Cooldown Reduction on her. 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.

With that in mind, here is our recommended Cooldown Reduction build for Morgana. You should start out with basic boots and probably some health and mana potions. Eventually, convert the boots to Sorcerer's Shoes, which increase your movement speed and provide you with an extra 15 Magic Pentration.

After that, here's what you should build.

Athene's Unholy Grail

By starting out with Athene's Unholy Grail, you're already halfway home because it gives you 20 percent Cooldown Reduction. Plus, it offers other very useful attributes, including mana regeneration, magic resistance, and 60 Ability Power.

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.

Morellonomicon

Now to finish off the process of maxing out Cooldown Reduction. By combining Morellonomicon with Athene's Unholy Grail, you double your reduction from 20 percent to 40 percent. Plus, Morellonomicon gives you 80 Ability Power and increased mana regeneration as well.

By taking care of Cooldown Reduction with just two items, you can focus on building up your damage with the final two vacant item slots, which brings us to our next item.

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.

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.
