World of Warcraft Item Upgrades
The upgrading of your equipment is a vital aspect of equipping your character. Upgrades increase item damage and enhancements.

They also provide bonuses and improvements. The Blacksmith can also sell them to you.
The upgrade button is available on any item. Each recycled item adds a level to the gauge for upgrading.
Weapon
When a weapon gets upgraded, it gets a base damage bonus, as well as a scaling factor which affects other stats. The weapon could also be upgraded with a number of upgrade components that provide additional features or effects and some even have distinct cosmetic effects. These upgrades can be added to weapons, armors, trinkets and gathering tools. They generally require that the equipment has an upgrade slot available and that it meets certain requirements. The upgrade component can be removed from a weapon, armor or trinket, but it will not be replaced. (Except for legendary equipment). Upgrade components can be recovered using a Black Lion Salvage Kit or Ascended Salvage Tool, or by using a salvage tool of high-end quality on the item the item.
A weapon can also be upgraded to include a Calibration attribute that improves certain stats, such as Weakspot damage or Crit Rate. This is accomplished through the Gear Workbench's interaction menu. Based on the tier of the weapon the process can be repeated up to four times.
After the weapon has reached its maximum level of improvement and is then reforged to add different bonuses and effects or improve specific stats. These upgrades can be applied simultaneously and their effects will differ based on how rare the weapon is.
Two Blacksmiths are able to perform these upgrades in the game: Blacksmith Iji on the Road to the Manor Site of Grace and Smithing Master Hewg at the Church of Elleh hub. Both require different upgrade materials: Smithing Stones for standard weapons and Somber Smithing Stones to alter the type of damage a weapon can cause.
It is generally advised to improve weapon damage first, followed by armor defense, and finally the other secondary stats as required by your build. It is not uncommon to see melee Druids upgrade their weapons before upgrading other equipment. This will increase DPS. More inspiring ideas is particularly applicable to enchantments that boost a weapon's stats and damage.
Armor
Item Upgrades allow players to improve the base stats of certain pieces of armor, weapons, trinkets and gathering tools. They can also provide other effects, such as an increase in damage or cosmetic enhancements. Item upgrades can be obtained through crafting, buying from NPC vendors, or in loot drops or as quest rewards.
Armor can be improved by visiting the Armorer NPC, and spending the appropriate currency. In most cases the armor can be upgraded to the next tier once an upgrade is applied. This can be done for all types of armor, though certain types of armor cannot be upgraded at all (such as the armor that is used as a starter in Great Sky Island).
Most armor upgrades increase the item's strength or defense by a small amount. Certain upgrade components, however can result in significant increases in defense or strength. This is particularly the case when upgrading epic items.
Certain upgrades offer specific abilities that can be activated when wearing armor. These abilities can prove useful in combat. For example, they can boost attack speed or block. Certain upgrades also offer passive effects, like cutting down on the amount of damage sustained when wearing armor, or giving you a a chance to dodge attacks.
Upgrades to armor can require several attempts, depending on the type of armor. If a player wants to upgrade Steelclash armor to Dragonscale The first attempt will result in a brand new Dragonscale armor that has an armor base defense of 59-67. The second attempt would result in the creation of a Dragonscale armor that has an initial defense range of between 67 and 77.
The Legend of Zelda: Breath of the Wild allows players to upgrade their armor sets to level 4. To do so players must visit each of the four locations known as Great Fairy Fountains in the game. Each of these locations contains an incredibly fair that can change the quality of an item of armor for you.
Despite popular belief it isn't a necessity in The Division 2. The reality is that certain armors have very significant increases in poison or curse, fire or magic damage reduction, which makes them extremely useful for certain builds. There are many other ways to improve armor stats besides upgrading the armor, for instance using the engineer attribute to increase armor penetration or the challenger trait to decrease total weight.
Potion
A potion can be upgraded by putting it in an brewing stand in order to unlock new effects. The upgrade unlocks a new effect tier, and can be re-used to increase the potency.
The potions also have an individual color, which can be set by the player via the /give. This color will affect the effect clouds' area-of-effect as well as the arrows that are generated. In Bedrock Edition the custom potion colour also applies to the particle effects of the potions.
The water bottle, the mundane and thick potions as well as awkward potions, now have a different brewing texture. In the Creative Inventory potion healing and weakness have been added. The addition of lingering potions which can be brewed using splash potions or Dragon breath. Also added is a thick potion that has the status effect of Mining Fatigue. Issues relating to this update can be tracked on the Bug Tracker.
Trinket
A trinket could be an inexpensive, small ornament or piece jewelry. It could be a necklace, ring or even a small flag that is used to identify a boat's lateen yard. It could also refer to a gilded trinket on the mast of a ship.
