4. The Blind Archer
You'll need Dark Souls' awesome DLC pack, Artorias of the Abyss, to see this one. Once you reach Oolacile Township in the DLC content, you can ascend a tower to talk with a massive giant archer who'll help you out by shooting down a dragon who was on his way to the shops and totally didn't want to kill you dead. Like all other NPCs in Dark Souls, the archer - Gough - can be attacked. He doesn't like this at all mind, and will promptly attack you if you choose to do so. What you probably don't know about Gough is that the archer is completely blind! If you equip the Slumbering Dragoncrest Ring, which muffles all sound you produce, Gough will walk around blindly trying to find you with no success!
