Item Slot Usage Optimization
Last Updated: September 30th 2016



.
In League of Legends, you can hold up to 6 items in your champion's item slots
To make the best use of them, you should try filling up all slots at all times.

This is because there are some items that are very gold efficient but not as slot efficient.  
These are usually the cheap items such as
Doran's BladeDoran's RingDark SealCorrupting PotionRefillable PotionVision WardBoots of SpeedTear of the Goddess and having them will greatly boost your early game power.
Therefore, a player who has empty item slots will lose out on their early advantage by not purchasing these items

But do keep in mind that all Doran's items and Potions have only 40% resell value so be mindful about buying too many of them

On the other hand, the following items have resell value of 70%

An Example of a Good ADC Build Order
(Go over these slowly to see which items are being replaced)
 
Doran's Blade Health Potion Start up with the Best Starting Items
Doran's Blade Refillable Potion Boots of Speed Vision Ward Long Sword Long Sword You should fill up all but 2 item slots with powerful but slot inefficient items
Doran's Blade Refillable Potion Boots of Speed Vision Ward Youmuu's Ghost Blade
Start building your first optimal item. Also try to spend all your gold at all times
Doran's Blade Refillable Potion Boots of Speed Youmuu's Ghost Blade

Always keep 2 item slots empty for your next item
Doran's Blade Refillable Potion Boots of Speed Youmuu's Ghost Blade Zeal Dagger
Doran's Blade Runaan's Hurricane Boots of Speed Youmuu's Ghost Blade

Sell Refillable Potion when necessary.  It already saved you enough gold after drinking just 2 charges
Doran's Blade Runaan's Hurricane Boots of Speed Youmuu's Ghost Blade B.F. Sword Pick Axe

Doran's Blade Runaan's Hurricane Boots of Speed Youmuu's Ghost Blade Infinity Edge
Now here's an exception to keeping 2 item slots empty
Doran's BladeRunaan's HurricaneBoots of SpeedYoumuu's Ghost BladeInfinity EdgeLast WhisperIf one of your recipe items such as Longsword is worse than Doran's Blade then you do not replace it
Chain Vest
Runaan's Hurricane Boots of Speed Youmuu's Ghost Blade Infinity Edge Last Whisper Doran's Blade is replaced by Chain VestNegatron Cloak though since they are both worth 720 gold each
Guardian Angel Runaan's Hurricane Boots of Speed Youmuu's Ghost Blade Infinity Edge Last Whisper Since most of the games end at this point, you should just get elixirs
Guardian Angel Runaan's Hurricane Statikk Shiv Youmuu's Ghost Blade Infinity Edge Last Whisper If you do somehow reach the ultimate late game, replace your boots for something better


So the main idea is to have no empty slots available at all times.
But we do have few rules!


1. Always buy combination of items that would make your gold balance closer to 0
  • This is to make sure that every hard earned gold is directly converted to power
  • Example: You have 800 gold.  Even though Doran's Blade is better than Longsword for adc you should get LongswordLongswordHealth Potion instead of Doran's BladeHealth Potion
2. Always buy advanced items over multiples of cheap items if you can afford it  
  • Example: if you have 1400 gold on your first back, you buy HexdrinkerHealth Potion instead of Doran's BladeDoran's BladeLongswordHealth PotionVision Ward.  
  • This is because advanced items are not as bad as basic items and they can be upgraded quickly to final items, which are much more powerful
3. Don't get items that you would have to sell soon
As mentioned in the Example of a Good Build Order, if you run out of item slots

  • You replace Doran's BladeDoran's RingCorrupting Potion with an item valued 700g or higher
Doran's Items indeed have more powerful stats than basic items (but not so much anymore).
Therefore, even if you would lose some money by selling Doran's Items, you should still get them
.

4. Special Restrictions
  • If you are going to purchase Tear of the Goddess, do not buy Doran's Ring (since this is just another scaling mp regen item).  This is because a champion who is mana hungry enough to buy Tear of the Goddess buys mana items at a discount, making 154 mana from Doran's Ring rather inefficient.  As a result Doran's Ring loses its gold efficiency and it will be only good as Amplifying Tome.  It also interferes with getting Tear of the Goddess early for mana stacking.
  • Doran's Shieldis currently an underpowered item which should be avoided in most cases.  It should be only purchased if you are laning agaisnt ranged AP champions who harass a lot with autoattacks such as Lulu, Kayle, and Teemo.  Otherwise Doran's Shield is outclassed by most of the basic items
  • Doran's Blade is also an inferior item to melee champions especially for those that do not stack AD because they do not autoattack minions as much.  It is only viable on ranged ADC.



You have now learned how to manage the item slots to optimize their usage
