Just Rocked Medusa 1V1 As well. It was going pretty fantastic at first too. Ran in, Fought medusa for a while, she dropped me after a bit So then I ran around and killed all the monsters. Then Went back to Fighting her, this is about the extent of the fight.

She couldn't hit me to save her life, and whats more. I wasn't using Lower attack weapons, and my character wasn't even 120 Parry. Drops her down to about 10% of her life left, and thought... I wonder If I can disarm her? All of A sudden a Flash Back occured of Disarming Assassins in the Citadel and them Hitting me for 1.5-2x the Damage. I figured what the hell and Disarmed her.
She went from doing 40 damage and missing 80% of the time to doing 80 Damage and missing 40% of the time........
Lets just say the Last 10% of her life was Hell.
