15 Reasons Why You Shouldnt Ignore Item Upgrade

WoW Upgrades - The Item Upgrader
Upgrades provide a guaranteed boost to certain stats. Each upgrade boosts the item level by +3. A random additional substat is also boosted alongside every upgrade.
The more modernized gear generally has a more value in trade as long as it meets low requirements (like the FB shield of the sorc) or has a high stat variance (like Eth titan weapons). These types of gear get less value from upgrading due to the requirement to roll for a perfect version.
Recycle Points
The item upgrader lets players upgrade their gear by offering the currency to an NPC. Upgrades can be applied to any type of armor or weapon. The item used to upgrade the item will be consumed and can't be used again. Upgrades can be used to create enchantments.
The upgrader is located in every major city, and is accessible at any time to upgrade your equipment. To keep your gear current, it is recommended that you visit the upgrader every several weeks.
Upgrades will cost more, based on the level of the item, but they will always be cheaper than buying new gear. For example, upgrading a Benthic chest to ilvl 385 will cost 20 recycle points, while buying a similar item from a different player will cost 105.
Valorstones
Upgrades are items that can be used to purchase tools, armor, weapon and accessory upgrades. Players can purchase them from item upgrader s NPCs for various currencies. They can also find them in random treasure lists. Once purchased, an upgrade can be applied to any tool, weapon, or armor. The button will display a preview of an item's next level of upgrade, if there are enough materials.
The upgrade cost depends on the slot of the item and the current item level and the weapon's price is higher than gloves or bracers for instance. Each upgrade cost 15 Flightstones and a few crests, with certain upgrades offering discounts to reduce the cost of Flightstones or crests used. Once an item has been upgraded to a certain level and is degraded, it can be sold and sold back to the upgrader for a lesser amount of both currencies.
Upgraders for items are available at many locations on the main island, as well as a few outposts. The NPCs offer an upgrade coupon and a possibility of obtaining a new recipe. The upgrade discount increases with the number of items being upgraded. It can also be increased by having players complete some specific achievements or complete quests.
In contrast to Cromwell in Baldur's Gate II is no item upgrader available in the beginning of Icewind Dale. The NPCs who are able to facilitate upgrades are only available through a variety means. This is both a benefit as well as a disadvantage.
In Season 3, the upgrade system was altered a bit, with several new features added. After an upgrade has been completed to a certain item level for an armor slot upgrading other items to the same item level will cost less. This is true regardless of whether the items come from another set of gear.
The discount applies to all accounts. In the same way, the amount of Harbinger Crests required to upgrade is also reduced and is not available until players reach certain milestones in their achievement.
Crests
When it comes to upgrading equipment in WoW players have a variety of options. They can use Flightstones that are a common upgrade currency that is available to all players, or crests, which are more specialized and consumed during upgrades at specific levels of items. Crests are an essential part of the Dragonflight gear progression system, which was introduced in 10.1, and come in 4 ranks.
The first thing to be aware of is that crests can only be used on gear of a specific rank, and that each rank has its own requirements for its upgrade path. The easiest and most straightforward upgrade is 15 crests. The most complicated upgrade could require as much as 20 crests, depending on the kind of gear that is being upgraded.
Players can obtain crests by working through content that is of the appropriate level, which involves walking around and performing outdoor activities for gear of lower tiers, raids or dungeons of all difficulties for higher-tier items or Mythic+ heroic raid bosses and dungeons for gear that is used in the endgame. The crests can then be exchanged with an upgrader for the item like Cuzolth or Vaskarn in Valdrakken to upgrade the item in the proper steps and routes.
The new currency system isn't too difficult to use, however it will bring some modifications to the upgrade process. For example, once an item reaches the highest level of upgrading for any rank (Explorer, Adventurer, Veteran, Champion, Hero, or Mythic) it will no longer require Flightstones to be upgraded. This is to allow players to get their gear up to the highest possible ilvl on all their characters instead of relying only on seasonal loot.
It's also essential to use crests in a wise manner, as they have only one purpose. For instance, it's a good idea make use of all your Whelpling-rank crests with the best gear you have available and then keep Drake and Wyrm crests to use for the next set of upgrades you plan to make. This is especially relevant for rings and trinkets that take up multiple slots on the character, which will only be able to avail the account-wide discount if all slots are full of high-quality equipment.
