These guys are pretty easy to parry due to the slow telegraph

i can pvp if these guys work like players

That DbK in the reference pic is a wide boye.

Damn things hit to hard...

Top 10 animes poise

I died to that one guy in a room with two spinning doors more than from most of bosses excluding smelter demon and pursuer o.O
They are lightning fast, agressive, very hard to dodge ( probably due to location ) and it comes down to luck in beating them...

I am very suspicious that the drakeblood knights wear a shield just like targray does when you consider the implication that the two orders of knights could have a common origin.

such a cool looking armor.

as long as you're able to break their stance and stun them for a bit, you should be able to follow up in some hits and take some chunks of their health off.
bait their heavy and rolling attacks then go for a crit if you're being careful
and keep in mind there are multiple drakebloods in the dragon sanctum, don't get overwhelmed or you'll die

in other words, Try two-handing and using the stone ring
