WoW Upgrades - The Item Upgrader
Upgrades provide a guaranteed boost to certain stats. Each upgrade boosts the level of an item by 3. Each upgrade also increases the random substatus.
Upgraded gear is generally more valuable, unless the item has a low requirement by nature (like FB sorc shields) or a high stat variance (like Eth Titan weapons). Upgrades are not as important for those with lower requirements due to the requirement to roll an exact version.
Recycle Points
The upgrader for items allows players to upgrade gear to a higher item level by supplying the appropriate currency to the NPC. Upgrades can be applied to any type of armor or weapon. The item used to upgrade the item will be consumed and cannot be used again. Upgrades can be used to create Enchantments.
You can upgrade your equipment anytime by visiting the upgrader in any major city. item upgrades is recommended to visit the upgrader once every few weeks, to keep your equipment up to date.
Upgrades will cost more, based on the item level, however they'll always be cheaper than purchasing new gear. Upgrades such as upgrading a Benthic chest up to ilvl385 will cost you 20 recycle points. Buying a similar item will cost you 105.
Valorstones
Upgrades are items that can be used to level up weapons, tools, armor, and other items. They can be purchased through NPCs who sell upgrades to item owners for various currencies. They can also find them on random treasure lists. Once an upgrade has been purchased it can be used on any weapon or tool using the help of The button will display a preview of an item's next level of upgrade, in the event that there are enough materials.
The cost of upgrading varies based on the slot for the item and the current item level. For instance, weapons will cost more than bracers, or gloves. Each step costs 15 Flightstones plus a set number of crests. Some upgrades offer a discount on the Flightstones. Once an item is upgraded to a certain degree, it can be degraded and sold back to the upgrader for a lesser amount of the two currencies.
Upgraders for items can be found in many places including the main island, as well as a few outposts. The NPCs provide both an upgrade coupon as well as the chance to obtain an entirely new recipe. The upgrade discount increases when more items are upgraded. It can be increased if players complete certain achievements or complete quests.
Contrary to Cromwell in Baldur's Gate II there is no upgrader for items available at the start of Icewind Dale. The NPCs that can assist with upgrades are only available through a variety of methods. This is both a benefit as well as an issue.
In Season 3, the upgrade system was altered a bit, with several new features added. Once a player has upgraded to a certain item level for an armor slot upgrading other items to the same item level, will cost less. This is true even if those items are from an entirely different set of gear.
The discount is applicable to all accounts. The amount of Harbinger Crests needed for upgrades is reduced as well, but is only available when certain milestones have been reached.

Crests
When it comes to upgrading gear in WoW, players have a variety of choices. They can make use of Flightstones, which are a common upgrade currency that is accessible to everyone, or crests, which are more specialized and consumed during upgrades on specific item levels. Crests are the main component of the Dragonflight gear progression system that was introduced in 10.1, and come in 4 ranks.
First, you should know that crests are only available for equipment of a certain rank. Each rank has an upgrade path that is different. The most basic and straightforward upgrade path costs 15 crests, while the most complex may require as many as 20 crests based on the kind of gear being upgraded.
Players can earn crests through finishing content at the appropriate level, whether that means walking around and doing outdoor activities for lower-tier gear, dungeons or raids of all difficulties for higher-tier items, or Mythic+ dungeons or heroic raid bosses for endgame gear. The crests can then be exchanged with an item upgrader, such as Cuzolth or Vaskarn in Valdrakken to upgrade the item in the proper steps and paths.
Utilizing these new currencies isn't too complicated however, the system will introduce a few changes to the overall upgrade process. When a piece has reached the highest level of upgrade for any rank (Explorer or Adventurer) it is no longer required to purchase Flightstones. This is to allow players to get their equipment to the highest possible ilvl on all their characters, rather than relying solely on seasonal loot.
It's also essential to use crests in a wise manner, as they are only used for one purpose. For instance, it's a good idea utilize all of your Whelpling rank crests with the best gear you have available, and then keep Drake and Wyrm crests for the next batch of upgrades you plan on making. This is especially relevant for rings and trinkets that take up multiple slots on the character which will only be able to benefit from the discount for all accounts when all of the slots are filled with top-quality equipment.
