Diablo 4 Item Upgrades
Items that are upgraded are components that can be inserted into weapons, armor and trinkets to provide an added benefit. They usually have more cost and require that the item be at an appropriate level.
Items that have extremely high requirements generally don't see any value in upgrading. This is particularly true for items like the eth Titans, which do not have a lot of variation.
Glyphs

Once you reach level 50 the action-RPG of Blizzard changes from its simplified campaign to the endgame. The game's mechanics start to change, with players being pushed into the Paragon Board leveling system, Nightmare Dungeons and brand new grinds to ensure that their class build is as strong as it can be.
Glyphs play a key role in this development. A higher upgrade level for a Glyph increases its stat attributes and its radius of impact on the Paragon Board. There are a variety of ways to gain these upgrades, but the majority of players will rely on the primary method: raiding Faction Crypts.
The Glyphs panel allows you to add glyphs to your text by selecting them from the menu on the left side of the screen. It initially displays glyphs in the font that your cursor is located, but you can view a different font or type style, and you can limit the glyphs available to a specific subset by selecting one of the options below Entire Font (for instance Punctuation displays only punctuation symbols). When you hover your mouse over the glyph, you will see its CID/GID and Unicode value in a tool tip.
The Glyphs Panel will keep track of your last 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 the glyph from the list by clicking on it with the right-click or Control-click and selecting Remove From Recent Glyphs.
Another feature of the Glyphs panel is that it permits you to create and edit a custom glyph set, which is beneficial when you must write certain types of text often. This will help you save the hassle of manually inserting each glyph when you require it.
A custom glyph set may include the maximum number of glyphs, 31 comprising both the base name and its suffix. The glyphs of the base name must be uppercase English letters (A-Z), lowercase English letters (a-z), European digits (0-9) and underscore (_). The glyphs in the suffix can include ligatures or contextual alternates which are variants that combine two or more characters into one visually unifying character.
Reroll Tokens
Upgrades are the primary mechanics that give extra bonuses to items, such stats. They are available in three different types: rerolling, leveling up and recycling. Each upgrade type comes with a unique bonus on an item.
Reroll Tokens allow players to 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 for players who want to upgrade an item, however the "potential" power of that item isn't what they want. Also, if the substats of the item aren't what they want to be.
Rerolling an item costs 1 token and will reset the upgrades, but keep the set, rarity and level intact. As an item is leveled up, its tier rises. The main stat of the item is increased by 3 points for each tier. A random extra stat will be boosted along with it. The ability to level an item to its highest possible level increases its level by 1.
The Blueprint Desk allows players to buy new Appliances, Ingredients and Decorations for their restaurant. Blueprints appear as envelopes at the start of each Preparation phase. They are opened by using Grab. Each blueprint has a unique icon, and each category of upgradeable items displaying various icons:
Some recipes require specific appliances or ingredients, and these can be purchased by selecting the Franchise Card from the Blueprint Desk. item upgrades and inputs are staples, meaning they won't be available in the Shop or on rerolls, while others have a greater likelihood of appearing if the franchise card of a particular brand is chosen at the Blueprint Desk. The Staple Pool is where all the items will stay for the duration of the game. When purchased from the Blueprint Desk, non-staple equipment is also transferred to the Seed Pool.
Recycled Items
The magic happens when you use the third "R," recycling. When you recycle a product made from recycled materials you are not only creating a better environment, but you are also giving the item a new life. The majority of recycled items are returned to the manufacturer from which they came to be remade into 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 is taken to a Materials Recovery Facility (MRF) where it gets separated and sorted into various components. From there it can be sold to end-user manufacturers to make something new. Remade products include:
This reduces the need to harvest, grow or extract raw materials to create something else. This in turn reduces the amount of damage that is caused to the natural world; fewer trees are removed and rivers diverted, as well as wild animals are displaced. upgrade item reduces the amount of pollution created by the dumped substances into our soil, water and air.
Recycled products help keep local businesses and jobs alive, especially for those who specialize in recycling materials. The demand for recycled items encourages companies to take part in this environmentally friendly effort.
The final reason to buy recycled products is that it requires less energy to create new products from recycled materials than to make them from raw materials. This is because the manufacturing process of creating a brand new aluminum can requires 95 percent more energy than production of an identical aluminum can made from recycled materials. Every little amount is important.
Leveling
Most units are able to level-up, giving them extra XP each time they fight or get attacked. This XP is used to unlock upgrades or increase the stats of the unit. Weapons are a good example of this, since they can be leveled up, increasing their damage and range.
Most leveling systems have a minimum amount of levels to be reached, but this can vary from game-to-game. Leveling is done by using coins or resources. The majority of systems use both to increase an item's level, but some only make use of one or the other.
In many games, leveling is an issue because it makes certain units too powerful and other units are unable be competitive. It is better to limit the amount of leveling a player can achieve, and require players to make a decision about what they want to upgrade and the reasons behind it.
