Boss Soul weapons are weapons which can be crafted from the souls that are dropped by some bosses throughout the game. There are multiple weapons which can be constructed from the souls (usually two). You can also consume the Boss Souls if you wish, but they are best reserved for the construction of these unique weapons - especially if you are going for the associated achievement/trophy.

The Process

To construct a Boss Soul Weapon you must do the following:

  1. Start with the base weapon type that's specified below and then upgrade it to +5 with Titanite Shards by using a blacksmith such as Blacksmith Andre in the Undead Parish.
  2. Upgrade the weapon further to +10 using Large Titanite Shards. To do this you must first give the Large Ember (found in The Depths) to Andre.
  3. Ascend the weapon by using the Giant Blacksmith in Anor Londo, 5,000 souls and the boss soul to then create the Boss Soul Weapon.
  4. You can then upgrade this weapon further by using Demon Titanite to a total of +5.

      When making one of these weapons, does it consume the soul, or can I make another weapon with the same soul?

              Is there a glitch on the remastered version, cause I’ve found the large ember given it to Andre but still can’t upgrade past +5 any tips cause I saved up all the boss souls I’ve got so far with making boss weapons for in mind

                Such a shame that most of the boss soul weapons in DS1 are a joke due to most of them having split damage, crappy/no scaling, or awful movesets (or in the case of Great Lord Greatsword, all of the above).

                Only ones really worth pursuing are Chaos Blade, Great Scythe, and if you're going for NG+ and beyond, Cursed GS of Artorias is good for New Londo and regular GS of Artorias is good for Catacombs due to it being classed as a divine weapon.

                I guess you could make a case for Moonlight butterfly horn for a mid-level INT-pure. Everything else is pretty much garbage.

                  "2. Upgrade the weapon further to +10 using Large Titanite Shards. To do this you must first give the Large Ember (found in The Depths) to Andre or another suitable blacksmith such as the Giant Blacksmith in Anor Londo."
                  The Giant Blacksmith doesn't take the Large Ember, only Andre does.

                    Don't use the Titanite Catch Pole for the Lifehunt Scythe as it only goes to +5 and can't be used for merging.

                        Honestly the life hunt and chaos blade are probably interchangeable because if your using one of them you should already have a build that is specified around that weapon.....but the scyth looks so much cooler

                            Heh... I don't use boss weapons, I appreciate the challenge of using weapons I scavenged from corpses.
