World of Warcraft - Item Upgrading
The upgrade of an item allows players to boost the gear rating of an item up 700 points, and then give it a bonus. Items can be upgraded by having them in inventory, and then taking them to the kiln.

Certain items are worth upgrading because of their unique stats. (For instance the perfect broken point armor that is rolled can be used in melee PvP). Other items like weapons don't change much after an upgrade and aren't worth the cost.
Weapons
Weapons can be upgraded to improve their numeric stats, such as crit chance, attack damage, PvE and PvP damage. Weapons also come with an unchanging bonus that increases the damage they deal per second. Additionally, many weapons have an added bonus that is activated when three or more of the same weapon are equipped on a single unit. In some instances, this bonus can add up to more than the amount of damage that a weapon upgrades on its own.
The cost of upgrading a weapon is based on the quality of the weapon and its current level. For example 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 required to upgrade a weapon will continue to increase until it is required to use the higher level of Smithing Stones, at which the amount will be reset to one.
Upgrades to weapons will also change the stats of their base. While this is generally beneficial however, it could have negative effects as well. For items that are only used in a certain build (Whistant's shield for FB sorcs, for instance) upgrading them could render them useless unless you have an extremely fortunate roll.
Upgrades can be made to armor items to improve their stats. In the case of chests or helms, this will increase the defense of its base, while a belt and gloves will increase their strength and dexterity. Armor has a rerolling option for its Enhanced Defense%. This means that it is able to reduce its value.
The upgrade template of a weapon will display the new stats that 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 the weapon gaining an attack damage of 3. However the 3% does not mean that it will be hit for 3 times less often as it is an absolute statistic.
A weapon can also be rerolled using the green button with arrows that circle in the menu for items. This will reroll an item and change its statistics, but it will not reset the weapon's level or bind it to account status.
Armor
A few tweaks to your armor can make a huge difference in your ability to survive. Certain sets offer massive boosts to poison or curse, fire or magic resistance, which can make traversing tough areas a breeze. In general, the greater defense you have for your character, the greater health you will receive from each point. So, it's best to upgrade your armor.
To improve your armor, head to any of the Great Fairy Fountains in the game. There are four in total, and each requires you to complete a special side quest involving the Stable Trotters musical troupe. After you've completed the main side quest and mastered the fountain that corresponds you'll be able to speak to any Great Fairy to open up the armor upgrading menu.
The amount of materials needed to upgrade each piece of armor is different. It is possible to use anything between three Red Chuchu jelly and 10 Rupees to upgrade the first armor piece, and anywhere between five Rubies or ten Fire-Breath Lizalfos Horns to upgrade each subsequent one. The Champion Leathers, for instance can be upgraded to a 5 defense rating, which will allow you to keep up in cold environments with a lot of foes. The Snowquill Headdress, on the other hand, can be upgraded as high as +20 defense so that you're able to withstand a rout with your comrades.
Be aware that armor can't be upgraded in the same manner as weapons, so you'll have to concentrate on enhancing it to increase physical power if you're Warrior or Spell Power when you're Mage. You should also save your armor upgrades to upgrade the armor that you will still be wearing at the end of the story, like the Ring of Lightning, Spectral Shield or the mask you wear in the final boss fight The Monter Parts Merchant Mask.
By giving the jeweler 10 Twinkling Titanite in Gerudo Town, you can gain some benefits to your armor. It is generally recommended to save 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 a few upgrades to the armor on your chest and helmets to let you escape some monsters.
Potions
Potions are bottled substances that, when consumed, give the user a temporary status effect. There are five kinds of potions with different effects and durations. Some potions may be upgraded, increasing their effectiveness. In addition, the effects of some potions can be enhanced by adding glowstone dust or redstone to them.
Potion upgrades cost a specific amount of XP. This can be earned by making them on a table or the chest of the Alchemist. The price of upgrades varies based on the type of potion used and the item's rarity as well as Mark Level.
To upgrade a potion simply right-click on it in your inventory. Then, select "Upgrade" from the menu. This will open an GUI where you can select the potion you want to upgrade and the amount of XP they will yield when upgraded. You can upgrade potions in batches of up to five at a time and their XP will be added to the total XP you have.
Once a potion is upgraded, it will not degrade until you re-use it, or break the bottle it's stored in. You can also change the name of the potion by clicking on it in your inventory.
Version 1.7.2 introduced a few modifications to the mechanism of potions. For instance, splash potions now have a duration of zero,08 seconds (this is not the same as 22.5 seconds shown on the hover display for the item). The table of potion can now be crafted with four Wood Planks and two Glass. This allows it to be used by players in Survival and Bedrock. Unlike the Java Edition, Bedrock edition potions are not able to be combined in cauldrons. Additionally, using a potentio on a full cauldron drains the potion and replenishes the bottle.
In addition, there are lingering potions that are brewed with dragon breath and splash potions. Redstone can also be added to potions that are lingering to increase their effects. item upgrade of potion ingredients is rearranged to look more like the Java Edition. New potions have also been added, for instance, the potion of leaping and decomposition.
Trinkets
A trinket is an ornament that is small and inexpensive or piece of jewelry. It could be a reference to an object or ornament that serves a purpose, but isn't particularly significant, such as a thimble. In some cultures, trinkets are used to symbolize affection or friendship, specifically between family members.
In addition to weapons, armor and potions, players are able to upgrade their trinkets. These can be upgraded by visiting an upgrade vendor and paying the appropriate currency. In contrast to other upgrades for items trinkets are able to be traded out at any time without losing their stats.
The upgrade vendors are found in major cities and in the capital of each zone, and in some instances in dungeons. Upgrades for trinkets are offered with tokens, gold or fragments of rare trinkets.
Upgrades are a cost-effective alternative to purchasing a new trinket. You can upgrade a trinket with as little as 12 tokens. The new trinket will come with the same base ilvl as the previous one, and will come with an additional upgrade bonus of 1.
When the old Trinkets are no longer useful, they can be upgraded. This allows players to increase their power and value over time. They can be traded among players, making them an alternative to gold.
Players must upgrade their most valuable items first. This means that the top-in slot items for each class are first upgraded then their secondary gear and other pieces of equipment that will not replace in the near future (such as a ring or an cloak). When choosing which items to upgrade, players should take into account the class's preferred stats. If Haste and Crit are two of the most important stats to tank players, then they should upgrade their helm, chest and shoulders.
Trinkets are able to be upgraded to a higher level once they no longer have value and the new trinket will receive an additional 1% upgrade bonus. However, a re-upgrade is likely to cause the trinket to be destroyed in the event that it is not salvaged with 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 buying an entirely new trinket.
