WoW Upgrades - The Item Upgrader
Upgrades give a guaranteed boost to certain stats. Each upgrade increases the level of the item by +3. A random extra substat is also increased with every upgrade.
Upgraded gear is generally more useful, unless the item 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 need to roll the perfect version.
Recycle Points
The item upgrader allows players to upgrade their gear by offering the currency to an NPC. Upgrades can be made on any type of weapon or armor. However, the item that is used to upgrade will be consumed for the duration of time and will not be able to be used again. Upgrades can also be applied to enhancements.
The upgrader can be found in all major cities, and can be accessed at any time to upgrade your gear. It is recommended to visit the upgrader at least once every few weeks, to ensure that your equipment is up to date.
Upgrades will cost more, based on the level of the item, however, they are always less expensive than purchasing new equipment. For example upgrading a Benthic chest to 385 ilvl will cost 20 recycle points, while buying a similar item from a different player will cost 105.
Valorstones
Upgrades are functional items which can be used to upgrade weapons and tools, armor and other accessories. They can be bought by players through NPCs who sell upgrades for items in exchange for various currencies, and can be found in random treasure lists. Once purchased, an upgrade is able to be used on any weapon, tool, or armor. The button will display the preview of an item's next upgrade level when there are enough materials.
Upgrade costs vary depending on the item slot, and the current item level. For instance weapons cost more than bracers, or gloves. Each step costs 15 Flightstones plus a set number of crests. Some upgrades give discounts on Flightstones. After an item has been upgraded to a certain amount and is degraded, it can be sold and returned to the upgrader for a lesser amount of both currencies.
A lot of locations offer upgraders for items in addition to the main island and a few outposts. The NPCs provide an upgrade discount and the chance to acquire a new upgrade recipe. item upgrades for upgrading increases as more items are upgraded. It can also be increased by having players complete certain achievements or quests.
In contrast to Cromwell in Baldur's Gate II, there is no upgrader for items at the start of Icewind Dale. The NPCs who can facilitate upgrades are only accessible through a variety means. This is both a benefit as well as a disadvantage.
In Season 3, many new features have been added to the upgrade system. Once a player obtains an upgrade to a certain level for an item in an armor slot, upgrading additional items to the same level will be less expensive, even in the event that they belong to another set of gear.
The discount is available to all accounts. The amount of Harbinger Crests required for upgrades is reduced too, but it is only available after certain milestones are reached.

When upgrading equipment in WoW, players have a variety of choices. Flightstones are an option that is accessible to everyone who wants to upgrade. Crests are more special and are utilized during specific upgrades to the level of an item. Crests are a crucial part of the Dragonflight Gear Progression System that was introduced in version 10.1. They come in four ranks.
The first thing to note is that crests are only able to be used on equipment that is of a particular rank, and that every rank has different requirements for upgrading. The easiest and most straightforward upgrade costs 15 crests. The most complex upgrade can require up to 20 crests, depending on the kind of gear being upgraded.

Players can earn crests through working through content at the appropriate level. This could mean doing outdoor activities, or by taking on dungeons and raids of any difficulty to earn lower-level gear or Mythicbosses for raids, or dungeons with heroic difficulty for gear in the endgame. These crests can then be exchanged at an item upgrader NPC, like Cuzolth in Dornogal, or Vaskarn in Valdrakken to obtain the appropriate upgrade pathways and steps.
The new currency system isn't too difficult to use, however it will bring some changes to the process of upgrading. For example, once an item reaches the highest upgrade level of any rank (Explorer, Adventurer, Veteran, Champion, Hero, or Mythic) it will no longer require Flightstones to be upgraded. This change allows players to upgrade their gear to the highest level possible for all their characters, instead of relying on seasonal loot.
It's also important to use crests wisely, as they only have one use. It is recommended to use your Whelpling-rank crests on the top-quality equipment you can find and keep Drake and Wyrm Crests for the next set of upgrades. This is particularly true for items like rings and trinkets that fill multiple slots on the character which will only be able to benefit from the account-wide discount when all slots are filled with top-quality gear.
