ho well does the Moredhau block work?

question says it all. will it block 100% attacks in duels, and what other functions are there? thanks

It works well but you have to put a little effort into it for it to be effective 100% and all features all listed on the cheat information page, the page that you saw the cheat on.

In my own personal experience it works almost flawlessly. The only times it doesn't work is if the target is swinging from wild directions outside the hitbox. These players are easy to recognize and adapt to however.
