World of Warcraft Item Upgrades
The upgrade of your items is a vital element of equipping your character. Upgrades boost the base damage and enhancements of items.
They also provide bonus effects and improvements. The Blacksmith can also sell them to you.
Players can recycle any item by pressing the upgrade button on it. Each recycled item adds one level to the upgrade gauge.
Weapon
When the weapon is upgraded it gains an initial damage bonus, as well as a scaling factor that can affect other stats. The weapon may also gain a variety of upgrade components, which provide additional attributes or effects and some even have distinctive cosmetic effects. These upgrades can be added to armors, weapons trinkets, gathering tools, and trinkets. Most require that the equipment is equipped with an upgrade slot and that it meets certain requirements. The upgrade component can be removed from an armored weapon, weapon or trinket, however it cannot be replaced. (Except for legendary equipment). Upgrade components can be retrieved with the help of a Black-Lion Salvage Kit or an Ascended Salvage Tool, or using a high-tier salvage tool on the item it self.
In addition to the basic upgrades, a weapon may be upgraded with the Calibration Attribute which improves certain stats like Weakspot Damage or Crit Rate. This is done through the Gear Workbench interaction menu. This can be done four times depending on the weapon's level.
When the weapon is at the maximum level of upgrade, it may be rebuilt using a variety of different upgrade types to improve specific stats or add other bonuses and effects. These upgrades can all be used simultaneously and their effects will differ based on how rare the weapon is.
There are two Blacksmiths in the game who can perform these upgrades: Blacksmith Hewg in the Church of Elleh hub area and Smithing Master Iji on the Road to the Manor Site of Grace. Both require different upgrade materials: Smithing Stones for standard weapons and Somber Smithing Stones for modifying the type of damage that a weapon inflicts.
In general, it is recommended to upgrade weapon damage first, followed by armour defense, then the other secondary stats that are required by your build. It is not unusual to see melee Druids upgrade their weapon before upgrading any other gear. This will increase DPS. This is especially relevant to enchantments that can be very efficient in increasing a weapon's damage and other stats.
Armor
Item Upgrades let players enhance the performance of specific weapons, armors trinkets and gathering tools. These upgrades can also give additional effects, like more damage or cosmetic enhancement. Item upgrades are available through crafting, buying from NPC vendors and loot drop, or as quest rewards.
The armor can be upgraded by visiting the Armorer NPC, and spending the appropriate currency. In the majority of cases an item of armor can be upgraded to the next tier once an upgrade is applied. This can be done for most types of armor, but certain items are not upgradeable at all (such as the armor used to start in Great Sky Island).
item upgrade provide a small increase to the item's defense or strength. However, certain upgrade components can offer significant improvements in defense or strength, particularly when upgrading an item that is epic.
Certain upgrades offer specific abilities that can be activated while wearing armor. These abilities can be extremely useful in combat. For instance, they can boost attack speed or block. Some upgrades have passive effects that can be beneficial, such as reducing damage while wearing armor or enhancing the chance to dodge an attack.
Depending on the type of armor, upgrading an item can require multiple attempts. If a player wishes to upgrade Steelclash armor to Dragonscale and the first attempt will result in a new Dragonscale armor that has the defense base ranging from 59 to 67. The second attempt will result in a brand new Dragonscale armor with the base defense between 67 and 77, and the list goes on.
The Legend of Zelda: Breath of the Wild lets players to upgrade their armor sets up 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 a powerful fair who can upgrade a piece of armor for you.
Contrary to popular opinion, armor in The Division 2 is not useful. Certain armors provide a significant boost to the reduction of the damage caused by poison spells, curses, magic or fire. This makes them very beneficial for certain builds. There are other methods to improve armor stats besides upgrading the armor, for instance using the engineer trait to increase armor penetrating or the challenger to reduce the total weight.

Potion
A potion can be upgraded by putting it in the brewing stand to unlock new effects. The upgrade unlocks a brand new level of potion effect and can be repeated for more tiers of potency.
The potion also gets an individual color code, which the player can select via /give, and that can affect the area-of-effect clouds as well as arrows produced by the potions. In Bedrock Edition the custom potion color is also applied to the particle effects of the potions.
The water bottle, the mundane, thick and awkward potions now have a brand new brewing texture. The potion of weakness was added to the healing potion in the Creative inventory. There are lingering potions available that can be brewed with splash potions or dragon breath and a strong potion that has the status effect of Mining Fatigue (duration 4 hours). Problems related to this update are maintained on the Bug Tracker.
Trinket
A trinket can be described as a small inexpensive piece of jewelry. It could be a ring, necklace or even a small flag to identify a boat's yard that is lateen. This can also refers to the trinket with gilded gold that is fixed to the mast of a vessel.
This bizarre trinket appears to be influencing the denizens of this maze, making them more common. At the moment it makes all types of mimic Xx more prevalent and gives every floor the chance to contain an ebony mimic. This trinket requires a small amount of energy to upgrade.
The enchanted Scepter's magic appears to alter the dungeon's environment and increase the likelihood of generating water and grass. At upgrade item can make X% of the floors fill with water or grass, but doesn't affect enchantments or the glyphs, cursed weapons, armor, or other items created to aid in the elimination of hazards.
The item, which appears like a newt's eyes, seems to affect your vision in a manner that goes beyond just narrowing your field of vision. This trinket, at its current level, increases the health gained by drinking healing potion and wells of life by X%, and gives you mind-sight on enemies within Y tile. This trinket is not stacked with the Higher Senses.
After completing the Mastery Cave, you can find Trinkets by beating Monsters and inside crates and chests in Skull Cavern. They can't be found in the Mines or Volcano Dungeon.
Place the trinket into the Anvil when it needs to be upgraded. This will have an unintended effect on the trinket either prolonging its life or enhancing its effects. You can reorge the Trinket as often as you like, but it will always be able to produce a new effect.
You can upgrade your Trinkets in the Alchemy Station by placing them into the Magical Catalyst. It will cost you 6 energy and increase the power of the trinket by only a tiny amount.
