Parrying

Summary

Players may parry melee attacks with shields as well as with two-handed weapons and martial manuals
Weapon parrying will result in the weapon taking durability damage similar to shields, albeit at a reduced rate
Players with both 80 Magery and 80 Parrying or greater may cast spells and meditate with a shield equipped (meditation rate will still be affected by the shield's meditation penalty)
Armor rating provided from shields is (50% * Shield Base AR) + (50% * Shield Base AR * (Parrying Skill / 100))
Provides a (50% * (Effective Parry Skill / 100)) reduction to Stamina losses that occur due to taking damage

Chance to parry a melee attack is (50% * (Parrying Skill / 100))
Successfully parrying an attack from another player or creature will reduce its damage by 75%
Successfully parrying an attack from another player, while wielding a two-handed weapon, will reduce its damage by only 50% however

Players have a (25% * (Parrying Skill / 100)) chance to parry a spell cast by a creature
Successfully parrying a spell from a creature will reduce its damage by 75%
You cannot parry spells in PVP

Players may now perform a Shield Taunt by double-clicking a shield they have equipped and targeting a creature (for Direct Taunt) or targeting themselves (Area Taunt)
Players may also activate Shield Taunt by using the [Taunt command if they have a shield equipped

Upon making a Directed Taunt towards a specific creature, a Parrying Skill check is made
On a Parrying Skill check success, the player massively increases the target's aggression toward the player for 20 seconds
The player will then have a 20 second cool down before they can make another Taunt attempt. patch April 2,2020
For the next 20 seconds, the player's equipped shield receives a 100% bonus to it's AR value when determining damage reduction
On a Parrying Skill check failure, the player must wait 5 seconds before making another Taunt attempt. patch April 2,2020

Upon making a Area Taunt (by targeting themselves), a Parrying Skill check is made
On a Parrying Skill check success, the player massively increases the aggression toward themselves for all creatures within 12 tiles for 10 seconds,
The player will then have a 30 second cooldown before they can make another Taunt attempt
For the next 10 seconds, the player's equipped shield receives a 100% bonus to it's AR value when determining damage reduction
On a Parrying Skill check failure, the player must wait 15 seconds before making another Taunt attempt

Note that after about 0.5% of Skill gained, a monster will stop giving parry skill gain requiring you to get new ones.
