Guild Wars 2 Item Upgrade
The statistics of an item are improved through upgrading it, also referred to as "upping". Each upgrade increment increases a stat linearly.

Players can recycle six items at once to gauge each item's upgraded component. The cost of recycling an item varies depending on its rarity and.
Upgrade components
In Guild Wars 2, an upgrade of an item can be a method to increase the stats on your weapon and armor. This can be achieved through a variety of methods, including by using upgrade components or by increasing the rarity of an item or its mark level. Many items can also be reforged to boost their value.
You can purchase upgradeable items throughout the game. They are available throughout all over the world, as well as rewards for missions. Players can also make them. The primary method to upgrade equipment is by making use of upgrade components, which are items that can be inserted into equipment. Most equipment has upgrade slots, and many require a certain upgrade level. Certain upgrade components offer specific bonuses while others provide a general bonus.
There are many types of upgrade elements in the game, such as universal upgrades, inscriptions and jewels. Universal upgrades, like gemstones and enchantments can be placed on any type of equipment, and offer less than upgrades for specific equipment. Glyphs can be placed in gathering tools, and provide various bonuses, from increasing the speed of an item's gathering to providing additional crafting materials.
To upgrade an item, select it from your inventory and open the Upgrade window. The preview will appear on the right side of the screen. It will display the expected stats after the upgrade. If you do not have enough of either the upgrade button will be marked as Blocked.
The number of upgrade components required for a given item is displayed in the upper-right corner of the Upgrade window. The cost of an upgrade increases depending on the upgrade level and rarity, however it can be reduced using many different methods, such as buying upgrades from a vendor or trading them to other players.
Almost all weapons can be upgraded by an upgrade to a prefix like an insignia or a rune, and a lot of them can be upgraded using a suffix upgrade. These upgrades change the name of the item to add an adjective, like "Radiant" or "Minor vigor. The only exceptions are the non-inscribable wands, the shields and foci from Prophecies and Factions campaigns, which are not upgradeable with any mods in any way.
Glyphs
Glyphs are a way to convey information via visuals. They move to grab the attention of the viewer and stimulate curiosity. The glyphs' animation mimics body language, making them more effective at conveying messages across language barriers. Glyphs can also enhance the recall of a message by evoking a familiarity in the brain.
Each glyph increases a stat's value by a certain range. This is shown on the item when you open it in the Glyph Storage. This is the maximum value that a glyph could increase a stat's value by, not the amount that it actually increases the stat by. The actual value of the glyph is determined by the tier and the quality of the item you're in awe of it.
Most upgrade components inserted into items are not able to be replaced or salvaged without dismantling the equipment in question, except for legendary equipment and upgrades. If you have a glyph or rune you don't want to use but it's not been applied to gear yet, you can move the item to a different piece by selecting the Upgrade Glyphs menu within the Glyphs Panel. This will create an Glyph Set that includes the chosen glyph.
You can take out any glyph with the help of a Black Lion Salvage Kit, or an Ascended Salvage tool. The item on which the glyph is located will be destroyed, however the upgraded item can be recovered with the glyph shards.
The addition of a glyph to an item could cause it to become unstable and the shards that are left of that glyph will disappear from your inventory when you remove the item. You can also add a glyph on your equipment to increase its value. For instance, the glyph Deferred Damage can store damage for the wearer and deal it slowly instead of all at once. This is beneficial for players who suffer lots of damage from their enemies but do not want to be overwhelmed.
Reroll tokens
Reroll tokens can be used to alter the affixes of weapons and equipment. They can be obtained from many sources, such as mystery boxes or rare drops from skulled monsters, or by killing bosses. Each reroll gives the player an affix randomly chosen and typically better than what they had before. Reroll tokens are also a good option to reroll stats on weapons, which can be upgraded for better damage or other perks.
Items that have been rerolled do not appear in the item upgrade menu, however, they are still eligible to receive upgrades. By pressing the "upgrade button", you can recycle the recycled items. This will alter the layout of the item's window and let up to six items to be chosen for recycling. The level gauge is increased by recycling an item. This amount is determined by the item's rarity and its level, which means items with higher levels are more useful to recycle than lower-level ones.
In addition to reroll tokens players can also use Star Remnants and Reroll Tokens to roll the weapon traits of an upgraded unit. Rerolls are based on a % chance to determine a weapon's trait. If it scores higher, then the weapon is upgraded. If it rolls lower the weapon is left as it was. Weapons can be upgraded up to 3 times.
Rerolling is a great option to upgrade an item. However, players must be aware of the fact that the total ilvl will be reduced by the number that it took to reroll it to the final level. This reduction effect is most effective with Diadems and ring items that do not have any other options for raising ilvls.
The system of rerolls has been criticised by players for being expensive and it's more equitable to let players pay for it with money or a food item that would allow them to change their builds without wasting time and effort. The developers aren't planning to implement paid rerolls at this point in the game's development. Instead, they're planning include a race change potion in the future.
Leveling
There are a variety of ways to upgrade an item. The first is to increase the upgrade amount that increases the value of an upgrade for a given stat. The second option is to increase the effect of an upgrade, which increases the damage or healing of a stat. Finally you have the option to upgrade the base item to a higher upgrade type. The upgraded item will keep its iLevel, but be upgraded to reflect the effects of the upgraded item.
It is crucial to remember that upgrades can be random. In item upgrading of cases, a better roll will come from the glyphs, but there are also chances for greater or special rolls. The type of item will determine the iLevel. If you upgrade a rare or unique item to a specific item type, it's likely to receiving an upper level.
Upgrades can be expensive Particularly if you're upgrading equipment from the standard track to the legendary. The cost will depend on the item's base iLevel and the number of upgrade levels it has. Certain upgrade tracks require crests in order to get to the next level.
If you're lucky your upgraded item will be at the highest level on its upgrade track, and will unlock a bonus effect. This will result in a significant increase in the value of the item. The bonus effect will change with each upgrade level. In general, the upgrade effect is increased by +3.
The iLevel will also change according to the upgrade path and base level. For instance, a weapon that is upgraded from a rare or unique item to an exceptional item will have a chance to be upgraded to the Enhanced Defense of the base item type.
