Diablo 4 Item Upgrades
Items upgrades are upgrade components which can be added to armors, weapons and trinkets to gain a bonus. They tend to be more expensive and require that the item is of a certain rank.

Items with very high requirements typically don't see any benefit in upgrading. This is especially true for items like the eth Titans, which don't have much variation.
Glyphs
Once you reach level 50 the action-RPG of Blizzard changes from its simplified campaign to the final game. After reaching level 50, Diablo 4's action-RPG shifts from its streamlined campaign to the final.
Glyphs are a major key to this progression. The higher the Glyph's upgrade levels boosts its stats and its radius of impact on the Paragon Board. There are several methods to gain these upgrades however the most popular is by raiding Faction Crypts.
Glyphs lets you add symbols to your text. You can select them from the menu at the left side of the screen. The Glyphs panel displays glyphs that are based on the font in which your cursor is currently located. You can alter the font or typestyle and narrow down the list to only include punctuation symbols using the option under Entire Font. You can view the CID/GID value and Unicode value of a glyph by moving your cursor.
The Glyphs Panel will keep the track of your last 35 glyphs and display them under Recently Used in the first row (you need to expand the panel to ensure you can see all 35). You can also remove them from this list by right-clicking or Control-clicking a symbol in the list and selecting Remove from Recent Glyphs.
Another benefit of the Glyphs panel is that it permits you to create and modify a custom glyph set, which is beneficial when you have to write certain types of text often. This will help you save the hassle of manually inserting each glyph every time you need it.
More hints may comprise up to 31 glyphs, including both the base name and its suffix. The base name must include uppercase English alphabetic letters (A-Z) and lowercase English alphabetic letters (a-z), European numbers (0-9) as well as underscore (_), and other glyphs. The glyphs that make up the suffix can include ligatures or contextual alternatives which are variants that combine two or more characters into one, visually unified glyph.
Reroll Tokens
Upgrades are the principal mechanic that offers bonuses on items, including extra stats. They come in different kinds: reroll or level up, as well as recycle. Each type offers a distinct set of bonuses that are added to the item.
Reroll Tokens let players alter an item's base power and the number of upgrades it has and are also used to reroll substats in ring. This is helpful if a player wants to upgrade an item, however the "potential" potential power of that item is not what they're looking for. Or if their item's substats aren't ideal.
Rerolling an item costs 1 token. It will reset the upgrades, but will keep the set, rarity and level intact. As an item is progressively leveled up, its tier rises. The main stat of the item will be increased by 3 points for each level. A random extra stat will be increased along with it. The ability to level an item to its maximum level increases its tier by 1.
The Blueprint Desk is a tool that lets players buy new appliances, ingredients, and Decorations for their restaurants. Blueprints are provided at the start of each Preparation Phase and appear as envelopes which can be opened by pressing the Grab. Each blueprint comes with its own icon, and each category of upgradeable items has a different icon:
Some recipes require certain Appliances or Ingredients, and these can be purchased by selecting a Franchise Card from the Blueprint Desk. Some Appliances and Inputs are staples, which means that they won't be sold in the Shop or on rerolls while others have a higher chance of being available when an appropriate franchise card is chosen at the Blueprint Desk. The Staple Pool is where all the items will be for the duration of the game. In the same way, non-staple equipment is transferred to the Seed Pool when it is purchased from the Blueprint Desk.
Recycled Items
The third "R," recycle, is where the magic really happens. You can benefit the environment by recycling a product made from recycled material. Most recycled items are sent back to the manufacturer from which they came to be remanufactured as a new item. We refer to this as "closing of the loop of recycling."
When a person places something into their recycling bin on the curb the item is sent to a Materials Recovery Facility (MRF) where it gets separated and sorted into different components. Then, it can be offered to manufacturers at the end of the line to be remade into something new. Remade products include:
This process helps reduce the need to grow harvest or extract raw materials from the Earth to create something new. In turn, this decreases the amount of damage that is caused to the natural world; fewer trees are trimmed down and rivers diverted, and wild animals are displaced. It also reduces the amount of pollution that is caused by dumping raw materials into our water, soil and the air.
Additionally Recycling products keep local businesses and jobs in business, particularly those that specialize in the production of goods made using recycled materials. This is due to the fact that demand for these products can encourage businesses to join in this environmentally friendly initiative.
The final reason to purchase recycled products is that it requires less energy to make new products from recycled material than to create them from raw materials. The process of manufacturing an aluminum container that is new requires 95% more energy than the process of making a can made of recycled materials. Every little part counts.
Leveling
Most units are able to level-up, giving them extra XP every time they attack or get attacked. This is used to boost the primary stat of the unit or unlock additional upgrades on the unit's development tree. Weapons are a great example, since they can level up and increase their damage and range.
Most leveling systems require a certain amount of levels to be completed, though this may vary from game to game. Leveling is achieved through the use of materials or coins. Most systems employ both, though some employ one.
In many games, leveling is a problem because it makes certain units too powerful and other units are unable compete. It is best to limit the amount of leveling that a player can perform, requiring players to make a decision about what they want to upgrade and the reasons behind it.
