Glitches

Soul and Item Duplication Glitch (Pre-Patch)

Go to a bonfire and ensure that no enemies are around you. Next, unequip your head slot item and equip either theCloranthy Ring or the Grass Crest Shield. Then, equip the dragon head stone with the soul/item you want to duplicate right after it. Then, facing forward, use your Dragon Head Stone again, but this time hold square, and then immediately turn around while still holding square and press down on the D-pad to switch to the item used.
Let go of square for a split second, then press it down again. To know that it worked, your character should be able to run around with their hands above their head.

Defeating the Black Knight in Undead Burg

Early on when you are not that strong of a character, the Black Knight in the Undead Burg can easily kill you with three or four strikes. An easy way to defeat him is to stock up on large arrows and throwing knives. You will be making use of the bridge you previously crossed while being targeted by firebombers. Run to the Black Knight and shoot him with an arrow to get his attention. As soon as he starts chasing you, flee back to the room that previously had two axe users and the undead knight. Turn around and close the door. Then, go out on the bridge, take out your bow and arrow, and start shooting him. When you run out of arrows, change to throwing knives. After a few moments the Black Knight will fall and you will gain a nice set of 600 souls. Once this is done the Black Knight will no longer respawn.
