Buckler. Here's brief explanation on how for each guy. Havel- run away until he one hands, and run away from him, as soon as he reaches within striking distance, hit the button as soon as his animation starts. For duel katakana. Just run away, as he reaches you he will most likely strike. As soon ad he reaches you, parry. Alternatively, there's 2 other easy parry methods. 1. Block his first strike and parry right after. Or 2. Back step his first strike and parry b right after. For rapier guy, id recommend partying rught after he rolls towards you. Just as he's coming out of it. Or block party works well
