The Item Upgrader in World of Warcraft
The War Within introduced Valorstones, and Harbinger Crests as two currencies to upgrade equipment. These currencies can be exchanged at the item upgrader NPCs, Cuzolth and Vaskarn.
Each item can be upgraded to the maximum level once for a slot. Upgrades to the slot are cheaper following. The pity system, which was introduced with The War Within, also reduces the extreme variance in upgrades.
Upgrades
Upgrades are components that improve performance or add new features. Upgrades can be earned or purchased in a variety of ways like events in the game or cash shop items.
Upgrades are only available for specific items. Unlike enchantments which can be added to anything but upgrades are only available to the item they are connected to. This means that upgrades cannot be applied to a weapon until it already has been equipped by the player. However, some items can be upgraded many times, bringing better benefit to the user of the item.

The mechanic of upgrades is fairly new. It was introduced in patch 4.1.0. The upgrade system lets players combine additional improvements to equipment to increase its power, from simple strength boosts to significant damage and defense increases. Upgrades are organized into tracks and each track has its own limit on the amount an item can be upgraded. These limits are designed to prevent players from scavenging low-keystone dungeons, and then upgrading their equipment all the way to.
Consumables, weapons, and armor are all upgradeable. The majority of gear is upgraded when it is dropped but certain items (such as Ornn's gear or the infant Dracolich pet) cannot be upgraded. The gear can be upgraded to higher levels by buying a recipe from an upgrade vendor, and then combining it with an item in the correct upgrade slot. The player can determine the amount of upgrades a piece of equipment can be upgraded by looking at its inventory icon, or by searching for the item in the shop.
The upgrade system has two major disadvantages. The one is that it may be difficult to determine the items that are upgradeable because the upgrade vendors do not always display all of them. The upgrade textures are created over the model which can hide enchantment details and other details.
Another disadvantage is that upgrades are expensive. Every step to an item's upgrade level is a specific number of Valorstones or crests, dependent on the item's slot and the level of the item. Weapons, for example, require more Valorstones and crests to upgrade. Items from the cash shop can help lower the cost.
Recycle
In the wake of growing awareness of how single-use products and consumption habits that are wasteful can contribute to environmental degradation, many people are shifting their shopping practices. Many are opting for high-end items that last longer or using their old gadgets as a workaround. Some are focusing on recycled items and seeking out the highest recycled content in their purchases. This will hopefully reduce the amount of resources required to produce and extract new materials, as well as create a more sustainable environment.
Recycling is an integral element of this process and it is now more accessible to consumers. Many products, including furniture and papers, are made from recycled material. This means they're made from recycled or scrap materials and it's simple to buy recycled products online or at the store. These products aren't just more eco-friendly and cost less, but they're also more affordable than their counterparts.
As an item levels up, it receives additional bonuses, in addition to its main stat boost. These bonuses are determined by its tier, and can vary from one type of bonus to the next. The higher the tier, the more bonuses you will receive.
As the world economy shifts from resource extraction to recycling and reusing more companies are making promises to produce greener products. Many of these are also insisting on using recycled materials and offering incentives for customers to recycle their goods. As the demand for sustainable products rises it is likely that we will see more recycled products in stores and on the shelves.
Rerolls
In Genshin Impact - or any gacha game for that matter Rerolling is a crucial tool. Rerolling allows players to try again for an item or character they like or want to play, whether because it's attractive or they think it's a great fit on their team.
Rerolls function by allowing players to refresh their items that are available for the current wave in exchange for a small amount materials. The cost of these weapons increase when the number of rerolls grows, but some items may not be available (for instance, characters who exclusively use ranged weapons will not see a melee item).
When an item is levelled up it is placed in the Staple Pool and gains extra bonuses. These bonuses are determined by the kind of item it is. For instance, an upgrade which boosts the weapon's main stat will also boost its additional stat. The extras will also change if the item is modified.
When a player is in enough stamina to complete an reroll, they will be able to press a button with the arrows that circle to swap their existing item for another one. The new item is of the same level of play, but different bonuses based on the type of item it was, such as an item from a book, sword, gun or watch.
Rerolling cannot change the levels of an item's bonuses. However the player may need to meet the minimum requirements for its special ability. This can make it difficult to obtain an item of high-level that offers the amount of bonus they want, but it does allow players to look for a different alternative in the future, without spending more resources.
The item will get an tier bonus which guarantees that it will receive a certain amount of stats in the near future. It is essential to only upgrade your equipment as far as you can, since additional upgrades won't make a difference.
Sets
A set is a group of objects that share a common property. They are frequently used in the mathematics field, and can be represented with the form of a notation, such as . Sets have many important properties such as the commutative and associative properties. These properties are crucial to understand how sets function and can be used in real-world applications.
In the game, items can be upgraded in sets to gain additional benefits. For example an armor set pieces can give an extra boost to the armour's defense, while a weapon could give an additional damage base. These additional stats will be applied after the base stat, and before percentages and flats. The additional stats can be a great way to add value to an item.
When upgrading an item, it will replace the previous base stat with the new one. For example an item that had 20 base damage is now sporting 40 base damage. The base armor and upgrade requirements will remain. This is a great method to purchase a premium item for a reasonable price.
The process of upgrading unique items can be very profitable, particularly when the item comes with an interesting modification. A rare belt with +5 IAS for instance can have a huge impact on a build's strength especially in early hell. It's an excellent way to increase the value of an item by incorporating an ideal or high-roll.
Item Upgraders function differently for unique, set and rare items. When an item reaches level 10, it will typically be upgraded to its base type. An upgrade of a unique armor item with max defense will result in a similar type of base for an armor item that is elite. This isn't a assurance, and in some instances, an upgrade might not change the type of item.
It is recommended to upgrade your BiS (Best in Slot) before moving onto non-BiS items. This will give players a solid base to build on when they're trying to level up. Then, they can focus on advancing tiers and gaining additional stats.
