{{Otheruses4|the weapon property that increases damage dealt by attacks|items' physical weights|WEIGHT (verb)}}

'''Weighting''' is a rare property on physical weapons that a increases the damage dealt by successful hits. There are two types of weighting: '''critical weighting''' increases the potential critical rank of the hit, and '''damage weighting''' increases [[health|HP]] damage.

Both types of weighting are measured by '''Combat Effectiveness Rating''', usually from 0 to 50 points.

[[Warrior]]s can {{mono|[[ASSESS]]}} weapons to determine their exact number of points of critical and/or damage weighting. {{mono|ASSESS}} also provides a verbal description, such as "''decently'' weighted to inflict more critical blows", which can be used as an in-character way to describe the property. The relationship between verbal descriptions and combat effectiveness is shown on the table to the right.

<span class="alert-warning">As of the [[/saved posts#Weighting, Padding, Sighting Revamp 2017|August 2017 update]], weighting has been changed to a [[item properties|Category C]] item property and can coexist with all other properties, including both critical and damage weighting on the same item.</span>

==Critical Weighting==
Critical weighting increases the critical severity of a successful attack by adding the Combat Effectiveness Rating to the raw HP damage before resolving the critical rank. A weapon with 10 points of critical weighting ("heavily weighted to inflict more critical blows") adds 10 extra phantom damage. '''The full critical weighting is added to each attack.'''

{{equation box|{{math|'''[[Critical|Max Critical Rank]] {{=}} ([[Raw damage|Raw Damage]] + Crit Weighting - [[Padding|Crit Padding]]) / [[Critical divisor|Armor Critical Divisor]]'''}}}}

Notes: Max critical rank is rounded down ([[trunc]]ated) to a whole number. Weighting values are ''never randomized'' as part of the max critical rank calculation: the full combat effectiveness value is always added. Padding values are randomized for values greater than 6 padding points of combat effectiveness; see [[padding]] for more details.

Characters have natural crit weighting derived from DEX bonus. GILCHRISTR's research indicates that 1 potential phantom damage is added for each 4 bonus. There are also some abilities that can temporarily bestow crit weighting, such as [[Sigil of Major Bane]]. These effects are applied additively to any weapon weighting and to each other. They apply to ranged and bolt attacks as well (which normally have no weapon-based weighting).

WEAPON SIZE PENALTY: SUMMATION(WEAPON SPEED + 1 - (OPEN OFF HAND?3:0) * 2) - STRENGTH BONUS, where SUMMATION is a seed 1 summation.  This penalty cannot go below 0 (i.e. cannot actually be a bonus).  "Open off hand" is considered true for two-handed weapons with an open left hand.

Stat-based crit CER bonus (DEX BONUS - WEAPON SIZE PENALTY) / 4.  (It is unclear if this can go negative, or how this is rounded, if at all).

For a lance, the user needs 56 STR bonus to benefit from their full DEX bonus.  For a spear, it's 20 STR bonus.

===Example===

You attack and hit a creature wearing soft leather armor for 15 raw damage.  Since the [[critical divisor]] of soft leather armor is 6, it would normally have, without any weapon weighting, a max crit rank of {{mono|[[trunc]](15/6) {{=}} 2}}. An attack with a heavily crit weighted weapon (10 points of combat effectiveness rating) will increase the total damage used to calculate the crit rank. To determine the max crit rank divide the sum of the raw and crit damage by the armor crit divisor and truncate the result. In this example it is {{mono|trunc[(15 raw + 10 crit) / 6] {{=}} 4}}. Therefore, the actual maximum crit rank possible has increased from 2 with a non-weighted weapon to 4 when weapon crit weighting is added. Bear in mind that this damage is not actually [[HP]] damage as yet, it is only used to determine the maximum critical rank. The final critical rank is subject to [[critical randomization]].

Critical weighting cannot increase the rank of a hit that would have been a critical rank 0 otherwise.

===Ambush===

[[Ambush]]ing from hiding has additional critical weighting based on training as well as a [[stance]] pushdown effect. The exact formula is not known. It has been estimated that a level 100 rogue fully trained in stealth skills receives around 40 to 50 points of weighting when ambushing with a dagger. This bonus only applies when ambushing from hiding, not open ambush/aiming.

==Damage Weighting==
'''Damage weighting''' is a property of a weapon that causes the weapon to inflict additional hitpoint damage on a target.  Damage weighting does not apply when calculating the critical outcome of an attack. The additional hitpoints from damage weighting are added at the end of the combat resolution calculations. There is no special messaging to indicate that damage weighting is a factor in the attack resolution. In order to determine the amount of weighting added to a particular attack requires calculating the non-damage weighted outcome and comparing this theoretical value to the actual result.

As with crit weighting, there is both a numerical value and a corresponding descriptive message associated with the level of weighting a weapon possesses. However, unlike critical weighting, which requires that the initial raw damage be sufficient to cause a minimum Rank 1 critical before activating, there is no such requirement for damage weighted weapons. Damage weighting will activate with all successful (endrolls greater than 100) attacks.

The amount of damage weighting added to an attack is either fixed or variable depending upon the level of weighting. Weighting levels from '''Lightly''' to '''Somewhat''' will always add the weapon's actual weighting. Weighting levels higher than '''Somewhat''' will add a variable amount of HP damage but will never be less than '''Somewhat''' equivalent weighting.

Adding damage weighting to weapons is NOT available through the [[premium point]] system. Damage weighted weapons are often available in [[player run shop]]s, through special merchants or events, or from private sales by other players. Because of their desirability weighted weapons can be quite expensive. High level weighted weapons can sell for tens of millions of silver or more.

Although not an intrinsic property of a weapon, damage weighting can also be added to [[melee]], [[ranged]] and [[bolt]] attacks by members of the [[Guardians of Sunfist]] society by activating the [[Sigil of Minor Bane]].

=== Damage Weighting Calculation ===
In order to determine the amount of weighting added to an attack it is necessary to know the weapon [[damage factor]] and the critical damage result. These values can then be used to determine the total theoretical damage (raw damage + critical damage). The amount of damage from the weapon weighting is simply (actual damage - theoretical damage).

==== Example 1 ====
<pre{{log2}}>
You swing a vultite longsword at a hill troll!<
  AS: +246 vs DS: +84 with AvD: +42 + d100 roll: +91 = +295
   ... and hit for 128 points of damage!
   Massive blow punches a hole through the hill troll's chest!
   The hill troll is stunned!
</pre>

In this example, the weapon damage factor is .275 ([[longsword]] vs. light leather: [[Armor]] Group 2). The raw damage from the attack is (weapon DF * (endroll - 100) which results in (.275 * 195) 56 raw damage. The critical damage can be found by looking up the messaging on the appropriate [[critical table]]. In this case, the critical messaging <i>Massive blow punches a hole through the hill troll's chest!</i>, which can be found on the [[crush critical table]], indicates a Rank 8 Chest critical with 65 points of damage. The total theoretical damage is (56 raw + 65 critical) = 119. The actual damage as shown in the combat messaging is 128. Therefore, the amount of damage weighting added to the attack is (128 actual - 119 theoretical) = 9 points of weighting.

==== Example 2 ====
In this example there is no critical damage. The messaging <i>Light slash to the hill troll's abdomen! Barely nicked.</i>, that is found on the [[slash critical table]], corresponds to 0 critical damage. Therefore, the only theoretical damage is the raw damage (weapon DF * (endroll - 100). In this example the raw damage is (.225 * 21) = 5. The difference between the weapon damage factor from examples I and II is due to the different armor worn by the hill trolls, as reflected in the different [[AvD]]s. The troll in Example II is wearing a leather breastplate (Armor Group 3). The weapon weighting is (actual damage - theoretical damage) which in this example is (13 - 5) = 8 points of weighting.

<pre{{log2}}>
You swing a vultite longsword at a hill troll!
  AS: +163 vs DS: +113 with AvD: +43 + d100 roll: +28 = +121
   ... and hit for 13 points of damage!
   Light slash to the hill troll's abdomen!
   Barely nicked.
</pre>
