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.

        if you look closely, you will see that the left half of the abyss greatsword looks exactly the same as the regular greatsword of artorias, while the second half is reminiscent of the cursed artorias greatsword. just thought this was a really neat easter egg.

          For those who want to get every boss soul weapon: It will take at least 3 playthroughs. Here's a list of everything you'll need:

          3 straight swords
          2 spears
          2 shields
          2 catalysts
          1 curved sword
          1 katana
          1 fist weapon
          1 axe
          1 hammer
          1 broken sword
          1 bow
          1 halberd
          153 titanite shards
          153 large titanite shards
          3 souls of Sif
          2 souls of The Moonlight Butterfly, Quelaag, Iron Golem, and Gwyndolin
          1 soul of Ornstein, Smough, Priscilla, Gwyn, Manus, and Artorias

          Some tips:
          • You can revert weapons that drop from mimics, specifically the Lightning Spear, Occult Club, and Enchanted Falchion, to take 36 titanite shards and 18 large titanite shards off the total. Since you have to do multiple playthroughs, you should revert the lightning spear twice.
          • Since soul gain increases on NG cycles, but store prices do not, farming should be done on the second or third playthrough to minimize the time spent farming. I recommend buying the large titanite shards from the giant blacksmith in Anor Londo, which will cost a total of nearly 600k souls.
          • Don't farm for small titanite shards. Farm for green titanite shards, and feed them to Frampt. The leeches in Blighttown can drop 5 green titanite shards at once, and each green titanite shard can be broken down into 5 small titanite shards by Frampt.

          It's quite a grind, but hey, the weapons are pretty darn cool. Hope this helps someone!

            if you use the soul glitch with humanity and give yourself 99 humanity makes this weapon do up to 400 basic damage, can do 800/1000 backstab

              Dark Souls ... the only game in which a simple wooden club is a thousand times easier and more effective than a mystical weapon, forged from the soul of an ancient legendary beast.

                Sanctuary Guardian's soul is only used for obtaining souls (12,000) and does not have a weapon you can create from it.

                The Taurus Demon doesn't have a boss soul, and it's weapon, the Demon's Greataxe, is a drop chance of I believe around 5%, you can farm the Taurus Demon's in Demon Ruins for a chance to get it.

                    Does the +10 weapon have to be normal upgrade path? or does it just need to be +10 equivalent (e.g. +5 magic)

The giant is only showing to make things Crystal in Modify Equipment and Reinforce Weapons shows nothing at all besides everything under my 10+ upgraded items. Can someone help me with this?
