Shields in Demon's Souls and Demon's Souls Remake are an integral part of your survival as you learn the game, since even a single blow past your guard can lead to your untimely demise. More than just a wall between you and the enemy, the player is presented with a wide variety of shield styles to choose from, allowing them the freedom to integrate their shield into their own personal playstyle. Shields are usually equipped on the offhand slot and absorbs damage from incoming attacks from enemies. Even though some weapons can also be used to block incoming attacks they always offer a much lower damage reduction.
Small Shields are a type of Shield that usually weigh very little and have the least form of protection from attacks. They are often used by players who prefer Parrying rather than Blocking.
Standard Shields usually have better stability and damage reduction than small shields, but at the price of increased weight.
These types of Shields usually weigh a decent amount and provide the best protection in the game.
