Knight's Honor

Knight's Honor is an achievement or trophy that is gained by collecting various unique weapons throughout Dark Souls. All weapons must be collected on a single character.

Most weapons can be collected in a single playthrough, but weapons crafted from boss souls can only be crafted once per playthrough. Because most boss souls offer the option to create two different weapons, a second playthrough would be required to craft all possible variants, with the exception on the Soul of Sif (see notes). Weapons from the DLC Artorias of the Abyss are not required for this achievement/trophy.

The following is a list of weapons and their respective locations:

Boss Soul Weapons
This list is roughly based on the order that the boss is encountered. Some important notes:
 * The base weapon must be upgraded to at least +10 before it can be ascended into a boss soul weapons.
 * Boss soul weapons can only be ascended at the Giant Blacksmith in Anor Londo.
 * To gain the souls of Ornstein and Smough, they must be defeated in a different order in seperate playthroughs.
 * The Soul of Sif is unique in that is can be crafted into 3 different weapons, however it appears only the swords are required for the achievement to unlock. The Greatshield of Artorias isn't needed.
