Item upgrades 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 boost additional stats.
The process of upgrading gear in The War Within requires a specified number of Flightstones and Crests Each item comes with an upgrade track. Each upgrade increases the cost of the next item by a specified amount.
Item Level
When an item is upgraded, its base stats increase in value. The value is the sum of an item's upgraded perks (attack magic attack and defense). Upgrades can be expensive dependent on who you employ and what you decide to do. This is due to the variety of perks that must be changed in order to upgrade an item.
The level of an item is a widely used measure of power, and is visible on all item tooltips. It is also used as a gating requirement while waiting to queue for dungeons and raids and scenarios, and to limit the amount of PvP gear players can wear (since PvP is limited to an lower level). Players can see their average level of item on their character sheet.
Using mouse click the next internet page can help players evaluate the power of equipment when deciding to purchase or sell. It's a measure of the damage and its quality. The level of the item can be used to compare items when examining a vendor's inventory.
The item level can be checked by pressing the ALT key on PC or using the left stick (L3) on XB1 and PS4. This will display the item's full description, including ilvl. It can also be found by hovering over an item using the mouse cursor, and then entering /itemlevel into chat.
There are several theories about how the calculation of the item's level is done. One theory is that the item level is a number that comes from a formula that calculates the amount an item's stats are worth. It is based on the fact that different advantages are valued differently and that gems found in sockets increase the value of the item. This process could result in a calculated value for the item's ilvl which is typically close to the actual Blizzard level of the item.
This is not the only factor that influences the ilvl of an item. The level of the area where the item dropped can also alter its stats. For example, it could increase the item's haste or crit score. 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 make or break an item for players. The game uses a variety of them in various ways to encourage players to play with multiple weapons, and also to stop one weapon from being "the best." The stats of a base weapon are enhanced by the weapon's stat modifications which are then increased by the player's skill.
The upgrades to an item can increase the stats of an item. The costs for upgrades are determined by the rarity of the item. A grey or white item for instance, will only be upgraded one time, while an item with rare tiers can be upgraded several times at higher costs.
Affixes are a different method to alter the stats of an item. They are stat boosters that can be added by the player to an item. Affixes are used to give items additional damage or special abilities (such as reviving dead or reducing cooling downs) or to make them unique by naming them.
All affixes are currently re-rolled by selecting them in the upgrade window pressing the green button. This process will cost the player a certain amount of gold as well as items which can be used to add to the upgrade gauge in the same way as the other options for rerolling.
In addition to Rerolling affixes and rerolls, players can select which of the available stats to be kept on an item when it is upgraded. The possible stat ranges of an item are based on the item level, but all items are guaranteed to have at least one stat within the specified range, unless it's an exclusive item or a God roll from a boss of a raid.
This is another aspect that can be modified by adding an option to upgrade the equipment without rolling the affixes or deciding which stats to enhance. As with the base equipment, it will have to be done per item and the interface for item comparison wouldn't display all possible stats simultaneously.
Item Luck
The Luck stat for a player adds up to increase the likelihood of finding items and the properties that are spawned from loot drops, and the intensity of those properties. However, it does not, directly affect damage or the ability to upgrade items. It merely gives players the chance to upgrade their equipment earlier in the game and is thus more valuable in early game runs than later ones because most players value higher weapon scaling and defenses over the raw damage gain.
In addition to influencing the discovery of items, Luck also increases the chance of being successful when upgrading items using 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 have the default Luck value of 40. These items can be enhanced with golden ingots or spined leather (depending on the type of material) to increase the value of 40 luck or to boost an item's existing Luck up to 140.
Additionally some items, such as the Hollow infused weapon can be used to increase the damage of any damage-dealing skill by 5percent. These items can be purchased in the shop or created with the right ingredients.
Item Failure
Upgrades to items are costly and not all upgrades will succeed. However, there are cash shop items which allow players to increase their chances of success or even prevent themselves from losing an item in the event that the upgrade is unsuccessful.
The rate of success of an upgrade is displayed in the Honing UI. The percentage represents the chance of successfully upgrading that item, and it can be increased by adding Additional Materials or Special Materials. There are limitations to how much success rates can be increased and the chance of an upgrade failing can't exceed 100%..
The performance of an upgrades is also influenced by the luck of the item. Every item has an initial success rate of 25%, and each item with Luck increases the chance of success by 5percent.
It is important to note that upgrade items are rendered above the inventory items, so enchantment glint and other effects may be obstructed by them. 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.
