Jagged Ghost Blade

Weapon type: Curved Sword

Attack type: Slash/Thrust

''Jagged blade weilded by New Londo ghosts. Violent thrust attack.''

''One of the cursed weapons. Inflicts damage to ghosts.''

As stated, this weapon can harm ghosts even if you're not cursed, which is good if you don't want to be cursed or if you don't have any Transient Curse. It has a chance to drop from killed ghosts, and has a high attack power of 140. Although it only has an E on Strength bonus, it's a very powerful weapon early in the game.
