Weapon upgrade

Weapon upgrades (also sometimes referred to as mods) are magically enhanced weapon parts that improve the characteristics of the weapon they are applied to. Weapon upgrades can be salvaged from a weapon and applied to another weapon, as opposed to weapon modifiers, which cannot be salvaged.

Weapons that do not have any upgrades on them are often called "clean," while those with the maximum value for their upgrades are called "perfect." Upgrading weapons does not change their value at the merchant.

A weapon can contain a maximum of 2 upgrades (one "prefix" and one "suffix"), plus one inscription.

A weapon has an upgrade on it if it has a prefix or suffix added to the weapon's name. For instance, if a Fiery Sword Hilt were applied to a Long Sword, it would be called a Fiery Long Sword. If a Sword Pommel of Defense were then applied, it would be called a Fiery Long Sword of Defense.

Shields, focus items, and wands found outside the Nightfall campaign cannot be upgraded. The modifiers on shields, focus items, and wands found in other parts of the game are fixed and can't be salvaged or replaced with other upgrade components. Upgrades have the following names:

Acquisition

 * Weapon upgrades can be salvaged from weapons that contain them by using an Expert Salvage Kit or Superior Salvage Kit.
 * Upgraded weapons obtained from collectors, promotions, or the PvP Character Creation process cannot be salvaged to get their upgrades.
 * However, you can add new upgrades to those weapons.
 * In some cases, you can salvage the upgrades of the collector item if it was already equipped with one, e.g. the Ascalon Razor.
 * Unique items cannot be salvaged for upgrades or upgraded whatsoever.
 * Fiery Dragon Swords, Icy Dragon Swords, and Fiery Gladiuses cannot have their sword hilts changed. Fiery Blade Axes and Icy Blade Axes can't have their Axe Hafts changed as well.
 * Vampiric and Zealous upgrades occur only on rare weapons.

Usage
Simply double-click the upgrade, and then click on a compatible weapon to equip it. Applying a weapon upgrade to the wrong type of weapon or an un-upgradable weapon will result in an error message. Applying a prefix upgrade to a weapon that already has a prefix upgrade will replace the old upgrade; likewise, applying a suffix upgrade to a weapon that already has a suffix upgrade will replace the old upgrade. You will receive a warning before the old upgrade is replaced.

Martial Weapons
1You can know when an unidentified weapon has one of the four elemental prefix upgrades by checking the weapon's Damage type. If the word "Dmg" appears with no other word before it, then the item has an elemental prefix. 2This will also lengthen the duration of Poisoning on yourself if you use Chilblains. 3Vampiric upgrades with "Life stealing: 1" are currently only available as unlocks from a Priest of Balthazar. Previously, vampiric upgrades were available on items of any rarity, allowing for nonperfect vampiric upgrades.

Staves

 * Hale blue observerd +22

Staves
