Enrys-Red Lantern

i got the 404 o doom, bro. but i found an invincible civilian in florence, once, though. couldn't assassinate him, just kept spamming square when i had the hidden blades equipped, and nothing. equipped my sword and hacked him up, and nothing. blood kept squirting out but all he did was back up. couldn't grab him, either. s'kinda weird. =|
