The Pursuer in Dark Souls 2 by the looks of things. My character just isn't able to do enough damage in a short enough space of time and can't take more than 3 hits during the course of the fight due to light armour and low health even in human form. Coupled with the weird way they handled rolling and parrying in the game, I just can't maintain the level of evasiveness I need to stay alive and if I do, I'm not doing enough damage to shorten the fight. I know exactly what to do, I just can't last long enough to do it. I pretty much need to spend ten minutes on the fucker without making a single mistake, which is not likely. The best part is that I'm fairly sure I need to defeat him in order to progress.
