Why We Are In Love With Item Upgrade (And You Should Too!)
WoW Upgrades - The Item Upgrader
Upgrades will give you a boost to specific stats. Each upgrade boosts the level of an item by 3. A random extra substat is also boosted alongside every upgrade.
Upgraded gear is generally more valuable, unless it is not required by nature (like FB sorc shields) or has a high variance in stats (like eth Titan weapons). Upgrades are less important for those with lower requirements due to the requirement to roll an exact version.
Recycle Points
The item upgrader allows players to upgrade gear to a higher level by providing the appropriate currency to the NPC. Upgrades can be applied to any type of weapon or armor. The item used to upgrade the item will be consumed and can't be used again. Upgrades can also be applied to enhancements.
You can upgrade your equipment at any time by visiting the upgrader in any major city. To keep your gear up-to-date it is recommended you visit the upgrader each few weeks.
Upgrades will cost more, based on the level of the item, however, they are always cheaper than purchasing new gear. For instance upgrading a chest piece from Benthic to 385 ilvl will cost 20 recycle points purchasing a similar piece from another player will cost 105.
Valorstones
Upgrades are items that can be used for weapons, armor, tools, and accessory upgrades. They can be purchased by players from item upgraders NPCs for a variety of currencies. They can also find them in random treasure lists. Once an upgrade has been purchased it can be applied to any weapon or tool with an The button will show the item's next upgrade level when there are enough materials.
Upgrade costs differ based on the slot of the item and the current item level. For instance, weapons will cost more than bracers, or gloves. Each upgrade costs 15 Flightstones and a variety of crests, with some upgrades having a discount to reduce the cost of Flightstones or crests that are used. After an item has been upgraded to a certain amount it is able to be downgraded and sold to the upgrader for a lower price.
Upgraders for items can be found in many places on the main island as well as some outposts. The NPCs provide both an upgrade discount and a chance to get a brand new upgrade recipe. The discount on upgrades increases according to the number of items being upgraded. It is also possible to be boosted by having players complete specific achievements or quests.

upgrade item to Cromwell in Baldur's Gate II is no upgrader for items at the start of Icewind Dale. Instead the NPCs that are available to help with upgrades must be acquired through various methods which is both an improvement and a drawback.
In Season 3, the upgrade system has been altered a bit, with some new features added. After the player has upgraded to a certain level of item for an armor slot, upgrading other items to the same item level, will cost less. This is true regardless of whether the items are from a different set of equipment.
The discount applies to all accounts. The amount of Harbinger Crests required for upgrades is reduced too, but it is only available when certain milestones are reached.
Crests
Players have several choices when it comes to upgrading their gear in WoW. They can use Flightstones which are a common upgrade currency that is available to everyone players, or crests that are more specialized and are consumed during upgrades on specific item levels. Crests are the main component of the Dragonflight gear progression system, which was introduced in 10.1, and come in four ranks.
The first thing to be aware of is that crests are only able to be used to purchase equipment of a particular rank, and each rank has its own requirements for its upgrade path. The simplest and simplest upgrade is 15 crests. The most complicated upgrade requires up to 20 crests, depending on the type of equipment that is being upgraded.
Players can earn crests through finishing content at the appropriate level. This could mean doing outdoor activities, or by doing dungeons or raids in all difficulties to get lower-tier gear or Mythicbosses of raids or dungeons with a heroic difficulty to obtain endgame gear. These crests can be exchanged with an item upgrader, such as Cuzolth or Vaskarn, in Valdrakken for the appropriate upgrade steps and pathways.
The new currency system isn't difficult to use, but it does bring some changes to the process of upgrading. For instance, once an item is at the highest upgrade level of any rank (Explorer, Adventurer, Veteran, Champion, Hero, or Mythic) it won't need Flightstones to be upgraded. This is to allow players to get their equipment up to the highest ilvl possible on all their characters rather than relying solely on seasonal loot.
It's also important to use crests wisely, as they have only one purpose. It is recommended to use your Whelpling-rank Crests on the best gear you can locate, and save Drake and Wyrm Crests for the next set of upgrades. This is especially relevant for items like trinkets and rings that fill multiple slots. The discount for the entire account is only applicable when all the slots on the character are filled with top-quality equipment.
