Weapon modifier

Description
Weapon modifiers are inherent effects which - as opposed to weapon upgrades - can not be salvaged.

Combat weapons may have up to one modifier, while caster weapons and offhand weapons may have up to two modifiers. Some weapons will have no modifiers, instead having one or more weapon upgrades. In addition to the modifiers listed here, blue weapons can also have the "precious" modifier, improving its merchant sale price, and the "highly salvageable" modifier, increasing salvage yields from that item.

Weapons will not come with more than one modifier for a particular property, even if the modifiers have different requirements. For example, you will not find a focus with both Armor +5 (while Health is over 50%) and Armor +10 (vs Giants), nor will you find a wand with both Energy +5 (while hexed) and Energy +14, Energy regeneration -1. The only exception to this rule are received physical damage modifiers on shields.

Weapons from collectors in high-level areas will have the maximum values for modifiers, making them the equivalent of dropped rare weapons. Note that some crafter, collector, and quest reward items can come with strange or otherwise unattainable modifiers, such as the Fiery Flame Spitter. This article lists only those available on dropped items, or on typical collector, PvP, and green items.

Available Modifiers
Note: modifiers not available on PvP weapons are denoted with an asterisk (*). In addition, available modifiers for PvP weapons may not be available in a specific combination, such as Reduces physical damage by 2 (while in a Stance) and Health +30 unconditional.

Combat Weapons
Axes, Bows, Hammers, Swords, Daggers, Scythes, and Spears may have at most one modifier. 1Energy -5 weapons are used by casters to "hide" energy. It is effective against energy denial in PvP and can also save energy when using energy-draining spells such as Rebirth. 2Unconditional Damage +xx% weapons were previously created through the abuse of an exploit. Also, it is rumored that some weapons that dropped during the first few weeks of gameplay "lost" their negative modifier (such as -5 energy or -10 armor while attacking) and thus became unconditional. 3Energy +5 modifiers can only occur on rare weapons that are available in Cantha.

Caster Weapons
Blue and purple staves and wands may have at most one modifier, and gold staves and wands may have at most two modifiers.
 * 1) Halves Casting Time (HCT) and Halves Skill Recharge (HSR) modifiers from multiple equipped weapons stack. Two 20% HCT items result in a 32% chance to HCT, plus a 4% chance to Quarter Casting Time. Skill recharge reduction is capped at 50% from multiple sources, so two 20% HSR simply result in a 36% chance to HSR.
 * 2) Staves with HSR modifiers no longer drop. Instead, new staves have HSR 10-20% as a base stat like damage and energy.

Shields and Focus Items
Blue and purple shields and focus items may have at most one modifier, and gold shields and focus items may have at most two modifiers. 1While these bonuses state "attacks", they actually are effective against all sources of damage. 2The damage type can be from either physical or elemental damage; that is, it can be Cold, Earth, Fire, Lightning, Blunt, Piercing, or Slashing damage. 3Focus items will only have a +1 modifier for caster attributes as listed below. Shields can have +1 for caster attributes as well as Strength and Tactics. In addition, Shields with +1 are not available on PvP items. 4Shields can have two "Received physical damage" modifiers with the following conditions: while in a stance, while enchanted, and while hexed. The two modifiers will stack if both conditions are met. A shield with "Received physical damage -x (Chance: 10-20%)" cannot have another "Received physical damage" modifier. 5Before the March 02, 2006 update, there were shield modifiers that gave -1-3 damage (Chance: 2-10%). They were replaced by the current modifiers that give -3-5 damage (Chance:10-20%).
