World of Warcraft - Item Upgrading
The upgrade option allows players to boost an item's gear rating up 700 points, and then add a final bonus. Items can be upgraded by keeping them in inventory before heading to the kiln.
Certain items can be upgraded for their unique stats (like a perfectly rolled breakpoint armour used in melee PvP) and others, like weapons, don't change much post upgrade and thus aren't worth upgrading.
Weapons
Weapons can be upgraded to improve their numeric stats, such as crit chance, attack damage as well as PvE and damage to PvP. Weapons come with a flat-rate bonus that increases damage per second. In addition some weapons come with a set bonus that activates when three or more of the same weapon are present on a single unit. This bonus may exceed the damage that a weapon upgrade alone can do.
The cost of upgrading a weapon's capabilities is contingent on the nature of the weapon as well as its current level. For instance an item with a rating of +2 will require two regular Smithing Stones to upgrade while the +3 model requires four. The number of stones needed to upgrade a weapon will continue increase until it is required to use the higher level of Smithing Stones, at which the number will be reset to one.
Upgrades to weapons also change the stats of their base. While this is usually an excellent thing but it can also have negative consequences too. In the case of items that only see use in a particular build (Whistant's shield for FB sorcs, for instance) upgrading them could make them unusable unless you get a lucky roll.
Items of armor can also be upgraded to increase their performance. This will increase the defense of a helm or chest while belts and gloves will increase their required strength and agility. Armor has a rerolling feature for its Enhanced Defense%. This means that it may reroll down to a lower value.

The upgrade template of a weapon will display the new stats it will gain upon upgrading along with the relative values of those stats. This means that an upgrade from a sword with 8 damage to an 11-attack-damage sword would result in a weapon gaining 3% of attack damage. However the 3% does not mean that it will hit 3 times less often because it's an absolute statistic.
Rerolling a weapon is possible by pressing the green button within the item menu with the arrows that circle. This will reroll the item and alter its stats, however, it will not reset the weapon's level or bind to account status.
Armor
A few tweaks to your armor could make a huge differences in your capacity to withstand. Certain sets can offer massive improvements in the resistance to curses, poison and fire as well as magic. This makes it easier to get through difficult areas. In general, the greater defense you have for your character, the more health you will get from each point. Therefore, it is recommended to upgrade your armor.
To upgrade your armor, head to one of the Great Fairy Fountains in the game. There are four Great Fairy Fountains in the game and to unlock each one you have to complete a side quest that involves the Stable Trotters. After you've completed your main quest and the corresponding fountains, you'll be able to talk to any Great Fairy in order to unlock the armor upgrade menu.
Each piece of armor can be upgraded up to three levels and the amount of material and Rupees required for each level will differ. You'll require anything from three Red Chuchu jellies and 10 Rupees to upgrade the first armor piece, and between five Rubies or ten Fire-Breath Lizalfos Horns to upgrade the next one. The Champion Leathers, for instance, can be upgraded to a 5 defense rating, which will allow you to remain competitive in frigid conditions with a large number of foes. The Snowquill Headdress, on the other side, can be upgraded as high as +20 defense to ensure you're able to survive a battle with your friends.
You can't upgrade your armor the same as weapons. If you're playing as a Warrior then you should concentrate on upgrading your armor to increase physical power or spell power. You should also save your armor upgrades to upgrade the armor you'll still be wearing at the end of the story, like the Ring of Lightning, Spectral Shield or the mask you'll wear in the final boss fight The Monter Parts Merchant Mask.
By giving the jeweler 10 Twinkling Titanite in Gerudo Town in Gerudo Town, you can unlock perks for your armor. You'll typically want to keep these upgrades for the weapon you'll be using to beat the game. For instance, the Longsword or Battleaxe. It's nevertheless beneficial to have some upgrades to the armor on your chest and helmets so that you can sneak around some monsters.
Potions
Potions are bottled substances that, when consumed, give the player an effect on their status for a short period of time. There are five different types of potions, each with a specific set of effects and durations. Some potions may be upgraded, increasing the effectiveness of their effects. In addition the effects of some potions can be enhanced by adding redstone or glowstone dust to them.
Potion upgrades cost a specific amount of XP, which can be earned by making them on a table or in an chest of the Alchemist. The cost of upgrading varies based on the type of potion used and the item's Rarity and Mark Level.
To upgrade a potion you need to right-click it in your inventory. Then select "Upgrade" from the menu. This will open a GUI that lets you choose the potion that you want to upgrade and the amount of experience they'll give you when upgraded. You can upgrade potions in batches of up to five at once, and their XP will be added to the total amount of XP you have.
Once a potion is upgraded, it will not be degraded until you re-use it, or break the bottle it is stored in. You can also change the name of the potion by clicking on it in your inventory.
There were some changes to the mechanics of potion in version 1.7.2. For example splash potions now have the duration of 0.08 seconds (this is not the same as the 22.5 seconds shown on the item hover display). The table of potion can now be constructed using four Wood Planks and two Glass. This allows it to be utilized by players in Survival and Bedrock. Bedrock Edition potions aren't compatible with cauldrons, unlike Java Edition. Additionally, using a potentio in a cauldron that is full drains the liquid and replenishes the bottle.
There are also simmering potions made with dragon breath and splash potions. Redstone is also added to potions that are lingering to increase their effects. The table of potion ingredients has been rearranged to look more like the Java Edition. New potions have also been added, for instance, the potion of leaping as well as decomposition.
Trinkets
A trinket can be an ornamental item that is small, cheap or piece of jewelry. It may also refer to an object or ornament that serves a purpose, but isn't particularly significant like a tiny thimble. In some cultures a trinket can be used to express friendship or affection between family members.
In addition to armor, weapons and potions, players are able to upgrade their trinkets. Upgrades can be obtained by paying the appropriate currency to an upgrade vendor. As with other upgrades to items, trinkets can be traded out at any time without losing their stats.
Upgrade vendors can be found at the capitals of each zone, and sometimes in dungeons. Upgrades for trinkets can be purchased with gold, tokens or fragments of rare trinkets.
Upgrading a trinket is a cost-effective alternative to purchasing new ones. It can be done by players for as little as 12 tokens. The new trinket will have the same base level as the old trinket however, it will also come with an additional bonus of 1% upgrade.
Trinkets can be upgraded when they are no longer useful and allows players to increase their power and value over time. They can be traded among players which makes them a good alternative to gold.
In general players should upgrade their most important items first. This means that the best-in slot items for each class are first upgraded, followed by their secondary gear and other equipment that they will not replace anytime soon (such as an earring or a cloak). It is also important to consider your class's preferred stats when selecting the items to upgrade. If Haste and Crit are two of the most important stats to tank players and they want to upgrade their chest, helm, and shoulders.
item upgrader can be re-upgraded to a higher ilvl once they no longer have value, and the new trinket will have an additional 1% upgrade bonus. However, a re-upgrade will ruin the previous trinket until it is salvaged using the Black Lion Salvage Kit or a higher-tier salvage tool. Upgrades to trinkets are more expensive than other upgrades but still less expensive than purchasing an entirely new trinket.
