To parry (in the context of the Evade/Block/Parry system) is to outright prevent a physical attack by intercepting it or knocking it aside with one's weapon, stopping the attack before the attack equation has even come into play. The check to determine whether an attack is parried occurs after the checks to determine whether the attack is evaded or blocked.

With the exception of runestaves, it is not possible to parry ranged (bolt spells, arrows, thrown weapons) attacks. This includes the chance to outright parry an attack as well as the loss of all parry DS.

Parry Defensive Strength (DS)

Parry Defensive Strength is calculated by adding the value of the appropriate Stance Bonus and a weapon bonus formula referred to as the Base Value. The Base Value formula requires 1 rank in the weapon held to be applicable or non-zero. The only exception to the Base Value weapon skill rank activation is the case of a runestaff, which is considered natively to provide 10 ranks in the appropriate skill, even with 0 training.

Parry 'Stance' Bonus

While there are several variations, depending on weapon category (one hand, two-handed, polearm etc.) for calculating parry DS, they each receive the same stance bonuses shown in the table below.

Stance DS Bonus
Offensive 0
Advance 10
Forward 20
Neutral 30
Guarded 40
Defensive 50

Calculating One Hand Parry (OHE/OHB/Brawling/Thrown Weapons) DS

Skill in one hand weapons (specifically: edged weapons, blunt weapons, brawling and thrown weapons) provides a bonus to one's overall defensive strength. There are two steps to calculate this value.

Step 1: Calculate the Base Value

Base Value = Weapon Ranks + trunc(STR bonus ÷ 4) + trunc(DEX bonus ÷ 4) + (Weapon enchant bonus ÷ 2)

Step 2: Calculate Parry DS

Parry DS = (Base Value * Stance modifier) + Stance Bonus

One Hand Parry Stance Modifiers

Stance Modifier
Offensive 0.20
Advance 0.30
Forward 0.40
Neutral 0.50
Guarded 0.60
Defensive 0.70

One Hand Parry DS Example

  • Weapon ranks: 60
  • STR bonus: 25
  • DEX bonus: 25
  • Weapon enchant bonus: 20
  • Neutral Stance Modifier: 0.50
  • Neutral Stance bonus: 30

Base Value:

60 weapon ranks + 6 STR + 6 DEX + 10 Enchant Bonus = 82

Parry DS:

(82 base * 0.50 stance mod) + 30 stance bonus = 71 Neutral Stance DS

Calculating Two-Handed Weapons (THW) Parry DS

Training in two-handed weapons provides a bonus to one's overall defensive strength. There are two steps to calculate this value.

Step 1: Calculate the Base Value

Base Value = Weapon Ranks + trunc(STR bonus ÷ 4) + trunc(DEX bonus ÷ 4) + Weapon enchant bonus

Step 2: Calculate Parry DS

Parry DS = (Base Value * Stance modifier) + Stance Bonus

Two-Handed Parry Stance Modifiers

Stance Modifier
Offensive 0.30
Advance 0.45
Forward 0.60
Neutral 0.75
Guarded 0.90
Defensive 1.05

Two-Handed Parry DS Example

  • Weapon ranks: 60
  • STR bonus: 25
  • DEX bonus: 25
  • Weapon enchant bonus: 20
  • Neutral Stance Modifier: 0.75
  • Neutral Stance bonus: 30

Base Value:

60 weapon ranks + 6 STR + 6 DEX + 20 Enchant Bonus = 92

Parry DS:

(92 base * 0.75 stance mod) + 30 stance bonus = 99 Neutral Stance DS

Chance to Parry

The odds for an outright parry are determined by comparing the defender's weapon skill to the attacker's level. Against a like-level foe, 2x training in the appropriate weapon skill will yield approximately a 5% chance to parry an incoming attack in stance offensive. Other factors that affect the chance to parry include:

A ranged attack can only be parried by bare-handed brawlers who have girded their arms with Brace (1214).

A bolt attack can only be parried with the proper weapon and knowledge of Spell Parry, with Brace, or if you are using a runestaff.
