You do not need to do anything to use Parrying. Parrying is automatically used any time a player is attacked while holding a shield or melee weapon. The attack may be blocked completely, partially or not at all.
To raise parrying, hold a shield in your hand and enter combat of some form. The skill is checked every time you are attacked
