Stun, also known as freeze, is a status effect that can be inflicted by both players and [[monsters]]. Stun can be applied for a number of turns by a [[Special Attacks|special attack]] or a normal attack by the player if the {{ItemIcon|Fighter Amulet}} is equipped. When an attack applies stun the current attack of the target is interrupted, including special attacks that are in progress. If the target is already stunned, it will not be applied again. When stunned, a stun timer counts down with a period equivalent to the target's attack speed. On completion of the timer the number of stun turns is decreased by one, and the status is removed if the resulting amount is zero. In addition to not being able to attack while stunned, a character cannot evade any attacks. | Stun, also known as freeze, is a status effect that can be inflicted by both players and [[monsters]].

=== Minimum Hit === | |||
<!-- JS source: character.js, function computeMinHit | |||
-->For [[Special Attacks]] the minimum hit varies depending on the attack. Otherwise, for normal attacks the base minimum hit starts at 1. To this base value, both modifiers for "+X% of Maximum Hit added to Minimum Hit" as well as increased flat minimum hit damage are applied. In addition, if a spell from the [[Magic#Standard Magic|standard spellbook]] is being used then element specific modifiers granting flat minimum hit damage for the same element as the spell being used are also included. The minimum hit is at least 1, and no more than the max hit. | |||
The minimum hit calculation for normal attacks is therefore: | |||
<math>\begin{aligned}\text{Min Hit} = \min(\max(&\left \lfloor 1 + \text{Max Hit} \times \text{Percentage Max Hit added to Min Hit Modifier} \right \rfloor \\ | |||
&+ \text{Flat Min Hit Modifier}, 1), \text{Max Hit})\end{aligned}</math> | |||

=== Damage Reduction === | ==== Damage Reduction ==== | ||
{{Main|Reference=Damage Reduction}} | |||
Damage Reduction (often abbreviated as 'DR') is a stat that does exactly what it suggests: It reduces the amount of damage taken by a player or monster. Unlike other combat numbers that are complex calculations, a player's damage reduction is determined by simply adding together all damage reduction bonuses the player has, whether from equipment or something else like a {{ItemIcon|Damage Reduction Potion|img=Damage Reduction Potion IV}} or {{PetIcon|Defence}}. | |||
A number of monsters in the game have natural damage reduction. With the exception of boss monsters, whose damage reduction is always at least 20%, a monsters' damage reduction is determined by their combat level. Some monsters also have [[Special Attack#Monster Special Attacks|special attacks]] which temporarily grant additional damage reduction, such as Stone Wall used by {{MonsterIcon|Terran}}. | |||

Whenever a player or monster with Damage Reduction greater than 0% would receive damage, instead the damage the damage they take is equal to: | |||
<math>\text{Damage Taken} = \left \lfloor \text{Base Damage} \times (1 - \left \lfloor \text{Damage Reduction} \right \rfloor) \right \rfloor</math> | |||
<math>\ | Where: <math> \left \lfloor x \right \rfloor </math> is the [https://en.wikipedia.org/wiki/Floor_and_ceiling_functions floor function]. | ||
Note that the [[Combat Triangle]] will affect how much damage reduction the player has if they are using a different style from the monster. | Note that the [[Combat Triangle]] will affect how much damage reduction the player has if they are using a different style from the monster. | ||
=== | ==== Critical Hit ==== | ||
With specific pieces of equipment, there is a chance that hits dealt by the player may become critical. When a critical hit occurs, any damage dealt by that hit will be increased by 50% - this increase is multiplicative with any other damage increasing bonuses currently in effect. | |||
The player's critical chance starts at 0% (at which point critical hits do not occur), and can be increased by the following: | |||
{{ModifierTable|MeleeCritChance,RangedCritChance,MagicCritChance|Critical Chance|true|}} | |||
==== Damage Per Hit, Average Hit, and Damage Per Second ==== | |||
If a player or monster successfully connects with an attack, the damage dealt will be a random integer value between their minimum and maximum hit. This random value is uniformly distributed, or in other words any value between and including the minimum and maximum hit is equally likely to be rolled. | |||
Damage Reduction is applied after this initial damage per hit is calculated, which means it is possible for a player to deal less than their minimum hit against a monster that has Damage Reduction. | |||
The player's average hit is thus: | |||
The | |||
<math> \ | <math>\text{Average Hit} = \frac{\text{Max Hit} + \text{Min Hit}}{2} \times (1 - \text{Enemy DR})</math> | ||
And their damage per second can be calculated as: | |||
<math> | <math>\text{DPS} = \frac{\text{Average Hit}}{\text{Attack Speed (Seconds)}} \times \text{Hit Chance}</math> | ||
=== | === Evasion Rating === | ||
The | <!-- JS source: character.js, function computeEvasion | ||
-->The calculation used to determine the player's evasion rating varies depending on the attack type the player is defending against. Each requires the calculation of effective skill levels, the formula for which is as follows: | |||
<math> \small{ | <math>\small{\text{Effective Skill Level} = \text{Standard Skill Level} + \text{Hidden Skill Level}}</math> | ||
In addition, the player's evasion modifier need to be known. This is the sum of all global evasion rating and the relevant attack type's evasion rating increases, provided from places such as [[Herblore#Combat Potions|Potions]], {{Skill|Agility}}, and {{Skill|Astrology}}. | |||
==== Melee and Ranged Evasion Rating ==== | |||
First determine the relevant defence bonus, this will be the melee defence bonus for the {{Icon|Melee}} evasion rating, or the ranged defence bonus for the {{Skill|Ranged}} evasion rating. These stats can be found in the Equipment Stats interface. | |||
Given this, the evasion rating is then: | |||
<math>\text{Evasion Rating} = \left \lfloor \left ( \text{Effective Defence Level} + 9 \right ) \times \left ( \text{Defence Bonus} + 64 \right ) \times \left ( 1 + \frac{\text{Evasion Modifier}}{100} \right ) \right \rfloor</math><!-- | |||
Note: Strictly the evasion rating calculation also includes an element of scaling when the 'globalEvasionHPScaling' applies, however this is only available through the 'Fleeting Defence' enemy passive, so currently does not apply to the player --> | |||
==== Magic Evasion Rating ==== | |||
The calculation for Magic evasion is slightly different from that for Melee and Ranged. The defence bonus used should naturally be the magic defence bonus. In addition, the effective defence level becomes a calculation that factors in both the player's effective Defence and Magic levels: | |||
<math>\small{\text{Effective Level} = 0.3 \times \text{Effective Defence Level} + 0.7 \times \text{Effective Magic Level}}</math> | |||
Then the magic evasion rating becomes: | |||
<math> | <math>\text{Evasion Rating} = \left \lfloor \left ( \text{Effective Level} + 9 \right ) \times \left ( \text{Magic Defence Bonus} + 64 \right ) \times \left ( 1 + \frac{\text{Evasion Modifier}}{100} \right ) \right \rfloor</math> | ||
