Upgrades to items can be used to increase the stats of a particular item. Based on the type of upgrade, it may increase an item's Mark Level or Rarity, and also boost other stats.
Each item comes with a track for upgrading it. Each upgrade increases the cost of the next one by a specific amount.
Item Level
The value of an item's stats base increases as it is upgraded. The value is the sum of an item's upgraded perks (attack magic attack and defense). Upgrades to items can be costly depending on the upgrader you choose and the type of upgrade you choose to do. This is due to the fact that many perks must be replaced to allow the item to get upgraded.
The level of an item is a commonly used measurement of power and can be seen on all tooltips for items. It also serves to limit the amount of PvP gear players can wear, since PvP is limited at lower levels. Players can view their average level of item on their character sheet.
When deciding to purchase or sell gear players can look at the level of an item. It's an indicator of the damage and quality. The level of the item can be used to compare items when evaluating a vendor's inventory.
On PC, you can check the level of the item by pressing ALT or by using the left stick on XB1 or PS4. This will show the item's full description, including the ilvl. You can also locate it by hovering over an item and typing /itemlevel in chat.
There are a few theories about how the calculation of the item's level is made. One theory suggests that the item level is calculated by formulas that determine the worth of an item's stats actually are. It is based on the fact that different advantages are valued differently and that gems in the sockets increase the item's value. This can result in an item's ilvl which is calculated and is typically very close to Blizzard's actual item level.
However, this is not the only factor which affects an item's ilvl, because the size of the area the item was dropped in could change the value of its stats, such as by adding a level to its crit rating or haste rating. This means that items dropped at higher levels will have higher value than items dropped in lower-level instances.
Item Stats
The stats of an item can be the difference between a good or bad item for players. The game makes use of a lot of them in a variety of ways to encourage players to play with multiple weapons, and also to stop one weapon from being "the most effective." The stats of a base weapon are increased by the weapon's stat mods that are in turn boosted by the player's level.
Upgrades to the item add by increasing certain stats of the item. The rarity of an item determines the cost of upgrading. A white or grey item, for example, will only be upgraded one time however, items that has rare tiers can be upgraded multiple times with more expensive costs.
Another method of altering the stats on an item is to use affixes. They are stat boosters that can be added by the player to an item. The affixes can be used to provide items with extra damage or other special abilities (such as the ability to revive dead or reduce cooling downs), or to differentiate them by adding a name.
All affixes can be re-rolled at the moment by selecting them in the upgrade menu and pressing the green button. This procedure will cost the player a certain amount of gold as well as items which can be added to the upgrade gauge in the same manner as the other rerolling options.
In addition to the possibility of rerolling affixes, players may select which stats they want to keep on an item when it is upgraded. The possible stat ranges for an item are based on the item level, but every item is guaranteed to have at least one stat within that range, unless it is an item that is unique or the result of a God roll from a boss in a raid.
This is another thing that could be changed by adding an option to upgrade the equipment without rerolling the affixes or deciding which stats to increase. But as with base equipment, this would need to be done on a per-item basis, and the interface for item comparison would not display all the possible stats either lost or gained at the same time.
Item Luck
The Luck stat of a player increases the likelihood of locating items as well as the properties spawned by loot and the intensity of these properties. It does not, however directly impact damage or the ability to upgrade items. It simply gives the player a possibility to obtain better equipment earlier in the game and is therefore more useful in early game runs as opposed to later ones, as most players prioritize greater weapon scaling and defense over the raw damage gain.
In addition to influencing item discovery, Luck also increases the chance of success when upgrading items with the Blacksmith. This is not to be confused with the Blacksmith's overall upgrade chance which increases with each item level and can be further enhanced by using an anti-material, such as a Scroll of Strength or a Jewel of Blessing.
Armor, shields and weapons can spawn or be crafted using the Luck property, which has the default value of 40. These items can then be upgraded with golden ingots, spined leather, or oak boards (depending on the type of material used) to grant an additional +40 Luck or to boost the Luck of the item up to 140.
Furthermore, certain items, such as the Hollow weapon that is infused with hollow can be outfitted to increase the damage of any damage-dealing skill by 5percent. These items can be purchased in the shops or made by using the appropriate ingredients.
Item Failure
Item upgrades are expensive and not all upgrades will succeed. However, there are cash shop items that allow players to increase their success rate or prevent them from losing an item in the event that the upgrade is unsuccessful.
The rate of success of an upgrade is shown in the Honing UI. The percentage represents the likelihood of successfully upgrading the item. This can be increased by using Additional Materials or Special materials. There are limits to the extent to which the success rates can be improved and the chance of an upgrade failing cannot exceed 100%.
The success of an can be affected by the luck of that item. All items have an average success rate of 25 percent and every item with Luck increases the chance of success by five percent.
The upgrade overlays for items are rendered above the items in the inventory. This may obscure enchantment effects and other effects. If you wish to disable the upgrade overlays, the config option decoration.renderUpgradeOverlays can be set to False in the Item Upgrader CORE client config.
