Elden Ring Parry Skill Guide, Notes & Tips

• A Number of shields will already have the Parry Skill so that players can perform a Parry which is is one of the main Combat maneuvers players can use when going against difficult Bosses or even in PvP and can be used as an effective offensive action combination when followed up with an attack. This gives players a chance at dealing a critical hit. It requires timing and patience to master, but provides more rewarding results than regular Dodging and guard countering, giving players a chance at a critical hit.
• A Shield with the Parry Skill is regured to be able to perform this action. The skill can be purchased on its own as an Ash of War. These are special items which enables you to replace Weapon Skills and Affinities of your equipment with new ones or even one at all.
  They can be applied to most Weapons and Shields, this allows players to adapt each type of armament to their respective Build and playstyle.
• The Ash of War: Parry Skill can be purchased from Knight Bernahl. It provides Standard affinity and the Parry Skill. Ashes of War can be equipped on Weapons and Shields to modify the Skill or an equipment, or to apply affinities that modify scaling values. When a Shield or Weapon in your left hand is equipped with Parry, it takes priority over the Ash of War on the armament in your right hand.
