Shield for parrying (Dark Souls 3)

Buckler or any other shield with a bulge.The buckler parry window above,personally, I liked to fend off the iron shield,he is easy,and the window of parrying is not bad,the main thing to naprositsya and be able to parry.

And it depends on how you're parrying. If you just bet the shields to parry the buckler and target, and if the block-bet, and better iron shield levelline. They have high stability and have the ability to withstand a blow and to catch blackguard.

Tsestus, not a shield, but the thing

The hand is not tsestus , but also knows how to parry

The newcomer is easier to start with small shields, buckler type of target etc, as the window frames, the biggest downside is that because of this, the owner of the buckler is easier to do Backstab during a parry.

As written at the top — easier with buckler and other small shields.
In General, each in their own way easier to parry; someone small shield, or tsestus, someone the average, and someone even kicks from Dougie.
