In our previous article What is Effective Health? we proposed an analysis on the effective health that items provide. Such an analysis can only be performed if a champion’s base health, armour and magic resistance are included; because they also contribute to effective health. For this reason Leona has volunteered as a test subject tank to make a thorough comparison between items.

For each of Leona’s levels we’ll calculate the effective health provided by each item and we’ll plot it against the other items taking into consideration Leona’s base statistics. The analysis is divided in two parts: physical and magical. Effective health depends on the value of armour or MR available so the best way of comparing items is to consider what kind of damage they are preventing.

In League of Legends there are 125 items divided in tiers and among the two existing game types: Classic and Dominion. The tiers are basic, advanced, legendary and consumable. Basic items can be bought with just gold, advanced items require at least a basic item to be bought while legendary items require at least one advanced item, consumables are items that once used are removed from a champion’s inventory.

There are 28 basic items, 62 advanced items, 26 legendary items and 9 consumables. From the whole 125 items, 97 are available in both game types. The remaining 28 are divided like this: 18 are available only in Classic and 10 only in Dominion. To buy the 125 items in League of Legends would cost 195778 gold.

The following table contains all items available in League of Legends. It can be sorted by clicking on a header and by holding the Shift key and clicking on additional headers to add other criteria.
The items’ list is up to date according to version 1.0.0.130 of the game.

In a previous article about the cost of statistics we couldn’t evaluate the cost of raising cooldown reduction (CDR), spell vamp (SV) and gold per ten (Gp10) because there aren’t any basic items that provide boosts to them. Moving on to advanced items we can find a few bonuses that will allows us to derive the cost of the mentioned statistics.

The table below lists all advanced items that provide CDR, SV and Gp10. Knowing the cost of the other statistics’ bonuses we can subtract their cost from the cost of each item until only the cost of CDR, SV or Gp10 remains. For better accuracy, the cost for the basic stats is taken from the items used in the recipe of each item. For example, Hextech Revolver’s AP cost is taken from Amplifying Tome; not from Blasting Wand.
