Diablo 4 Item Upgrades
Item upgrades are upgrade components that can be inserted into armor, weapons or trinkets to offer a bonus. They usually come at more cost and require the item to be at an appropriate level.
Upgrades are not usually worth the cost for items that have high requirements. This is especially applicable to items that don't roll a lot of variance like Eth titans.
Glyphs
Once you reach level 50 the action-RPG Blizzard's shifts from its streamlined campaign to the endgame. This is when things really begin to change, with players being pushed into the Paragon Board leveling system, Nightmare Dungeons, and new grinds to ensure that their class build is as strong as possible.
Glyphs are an essential component to this progression. A higher upgrade level for a Glyph increases its stat attributes and the radius of its effect on the Paragon Board. There are several ways to obtain these upgrades however the most popular is through raiding Faction Crypts.
The Glyphs panel lets you insert glyphs into your text by selecting them from the menu on the left of the screen. It initially displays glyphs in the font where the cursor is placed, but you can view another font or type style, and limit the glyphs available to a smaller subset by selecting an option from the options below Entire Font (for example Punctuation shows only punctuation symbols). You can view the CID/GID value and Unicode value of a glyph by moving your cursor.
The Glyphs Panel will keep track of your most recent 35 glyphs, and display them under Recently Used in the first row (you must expand the panel in order that you can see all 35). You can also remove a glyph from this list by clicking on it using the right-click option or Control-click, and then selecting Remove From Recent Glyphs.
The Glyphs Panel also allows you to design a custom set of glyphs. This is useful if often need to type certain text types. This will help you save the hassle of manually inserting each glyph when you require it.
A custom glyph set can contain the maximum number of glyphs, 31, including both the base name and its suffix. The base name must contain uppercase English alphabetic letters (A-Z), lowcase English alphabetic letters (a-z), European numbers (0-9) and underscore (_) and other glyphs. The suffix can include ligatures or contextual alternatives. These are special variants which combine two or more letters into a single glyph.
Reroll Tokens

Upgrades are the primary mechanics that offer an additional benefit to items, including stats. They are available in three different types: rerolling and leveling up and recycling. Each type provides a different set of bonuses that are added to an item.
Reroll Tokens allow players to alter the base power of an item and the number of upgrades available and are also used to reroll ring substats. This is useful for players who want to upgrade an item, however the "potential" power of the item isn't what they want. Or, if their substats of the item aren't what they want to be.
Rerolling an item costs 1 token and will reset the upgrades, but will keep the rarity, set, and level intact. As an item is progressively leveled up, its tier rises. The main stat of the item is boosted by 3 points for each tier. An additional stat is also boosted with it. The ability to level an item to its max possible level increases its tier by 1.
The Blueprint Desk allows players to purchase new appliances, ingredients and decorations for their restaurant. Blueprints appear as envelopes at the beginning of each Preparation phase. They can be opened using Grab. Each blueprint comes with its own icon, and each category of upgradeable item displays an icon that is distinct from the others:
Selecting a franchise card from the Blueprint Desk will allow you to purchase certain appliances or ingredients needed in certain recipes. Some Appliances and Ingredients are considered to be staples, which means that they will never be available at the Shop or through a reroll, while others have a higher chance of being available if a particular Franchise Card is chosen from the Blueprint Desk. The Staple Pool is where all the items will stay for the duration of the game. The same goes for non-staple equipment. 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 help 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 remade as a new item. This is what we call "closing the recycling loop."
When a person puts something into their recycling bin on the curb, it gets sent to a Materials Recovery Facility (MRF) where it is separated and divided into its different components. Then, it is transferred to manufacturers who will re-make the product. Items that are usually transformed into new products include:
This process reduces the necessity to harvest, cultivate or extract raw materials to create something else. This helps reduce the harm done to nature; fewer trees are cut down, rivers are diverted, and wild animals are forced to move. item upgrading reduces pollution from the disposal of raw materials into our soil, water and the air.
Purchasing recycled products helps keep local businesses and jobs thriving particularly for those who specialize in recycling materials. The demand for recycled items encourages businesses to participate in this environmentally friendly effort.
A final reason to purchase recycled products is that it takes less energy to create new products from recycled materials than it does to create them out of raw materials. The manufacturing process for a new aluminum container requires 95% more power than the manufacturing of a can made of recycled material. This is why every little bit counts.
Leveling
Most units can level up which grants them additional XP each time they fight or are attacked. This XP can be used to boost their primary stat or unlock other upgrades on the unit's development tree. Weapons are a great example of this, as they can be leveled up to increase their damage and range.
Most leveling systems have a minimum number of levels that must be completed, however it can differ from game-to-game. Spending coins or materials is the only method to level up. Most systems use both to boost an item's level, but certain systems only employ one or the other.
Leveling is a major issue in a variety of games since it makes some units too powerful, whereas other units can't compete with them. Limiting the amount of leveling players are allowed to do will force them to consider what they want to upgrade, and why.
