User blog comment:Brainwasher5/Highest damage possible?/@comment-4858354-20120428001500

found this on the dark souls wikidot, under the dragon torso stone, like the guy said it's obviously a glitch, and i've yet to test it, but if it works this is definitely close to the highest damage possible

Dragon Bow Glitch
Obvious bug flaw in the game which i hope gets patched. Place a bow in your left hand and two-hand it while dragon torso stone is on. This will cause the game to glitch and add the bow's damage to your fists damage (Happens without dragon torso just better with the torso stone) A composite bow+15 on 40dex should have ~450 damage + your base of 50 damage. Now add every single damage buff including dragon torso to that 500 damage and you get the dragon bow glitch. Only works while backstabbing and will not work with hornet ring against other players and NPCs. This glitch will do about 15,000-20,000 damage against other players or about 20,000-30,00 damage against main game enemies with hornet ring.

like i said it is a glitch and i haven't tested it yet, but there ya go.
