Why You Should Concentrate On Enhancing Item Upgrade
WoW Upgrades - The Item Upgrader
Upgrades provide a guaranteed boost to certain stats. Each upgrade boosts the level of an item by 3. A random additional substat is also increased with each upgrade.
The upgraded gear is usually more useful, unless the item is not required by nature (like FB sorc shields) or a high stat variance (like eth Titan weapons). Upgrades aren't as important for the latter due to the need to roll an exact version.
Recycle Points
The item upgrader enables players to upgrade their gear to a higher item 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 used to create enchantments.
The upgrader can be found in all major cities and can be accessed anytime to upgrade your equipment. To keep your gear current it is recommended that you visit the upgrader each few weeks.
Upgrades will cost more, based on the level of the item but they will always be cheaper than buying new equipment. For instance upgrading a Benthic chest to ilvl 385 will cost 20 recycle points while purchasing the same item from a different player will cost 105.
Valorstones
Upgrades are items that can be used to upgrade weapons and tools, armor and accessories. Players can purchase them from NPCs of item upgraders for various currencies. They can also find them on random treasure lists. Once purchased, an upgrade is able to be applied to any weapon, tool or armor. button, which displays an image of the item at its next upgrade level when the player has enough materials.
The cost of upgrades varies based on the slot of the item and the current item level, with weapons costing more than gloves or bracers for instance. Each upgrade cost 15 Flightstones and a variety of crests, with certain upgrades having a discount to reduce the cost of Flightstones or the crests used. Once an item is upgraded to a certain amount and is degraded, it can be sold and sold back to the upgrader for a lower amount of both currency types.
Upgraders for items can be found in many places on the main island as well as some outposts. The NPCs provide both an upgrade coupon and a chance to obtain the latest recipe. The upgrade discount increases with the number of items that are being upgraded. It is also possible to be increased by having players complete some specific achievements or complete quests.
Unlike Cromwell in Baldur's Gate II is no upgrader for items in the beginning of Icewind Dale. The NPCs that can assist with upgrades are only available through a variety means. This is both a benefit and an issue.

In Season 3 the upgrade system was tweaked a bit, with several new features added. After a player has earned an upgrade to a particular item level for a particular armor slot, upgrading other items to the same level will cost less, even if they belong to an entirely different set of gear.
The amount of Valorstones required for upgrades is reduced, and the discount is affixed to all accounts. Similarly, the amount of Harbinger Crests needed for upgrades is also reduced and is not available until players reach certain milestones in their achievement.
Crests
When it comes to upgrading gear in WoW players have a variety of choices. They can choose to use Flightstones which are a common upgrade currency that is available to all, or crests, which are more specialized and are consumed during upgrades at specific item levels. Crests are an essential part of the Dragonflight gear progression system that was introduced in 10.1, and come in 4 ranks.
First,
item upgrades must be aware that Crests are only available to equipment that is that is of a particular rank. Each rank comes with an upgrade path that is different. The simplest and simplest upgrade route costs 15 crests while the most complex can require as much as 20 crests based on the type of gear that is being upgraded.
Players can earn crests through completing content at the appropriate level. This could mean engaging in outdoor activities or completing dungeons and raids in all difficulty levels to obtain lower-level gear or Mythicbosses of raids or dungeons with heroic difficulty to obtain endgame gear. The crests can then be exchanged with an upgrader for the item, such as Cuzolth or Vaskarn, in Valdrakken to upgrade the item in the proper steps and pathways.
The new currency system isn't difficult to use, but it brings some changes to the upgrade process. Once a piece of gear has reached the highest level of upgrade for any rank (Explorer or Adventurer) it no longer requires Flightstones. This allows players to upgrade their gear to the highest level possible for all their characters rather than relying on seasonal loot.
Another important change is that crests only have one purpose and it's crucial to use them wisely. For instance, it's a good idea make use of all your Whelpling-rank crests on the best gear you have available and save Drake and Wyrm crests to use for the next set of upgrades you're planning to create. This is especially true for items such as trinkets and rings that fill several slots. The discount on the account will only apply when all the slots on the character are filled with high-quality equipment.
