Fragment of Shushu Soul

 is a subcategory of miscellaneous.

Obtaining

 * Dropped by
 * Monsters (while having a Shushumi equipped)

Uses

 * Similar to Smithmagic Runes, Fragments of Shushu's soul are associated with different elements and, when applied to your Shushumi, they give it added bonuses.
 * Unlike Smithmagic Runes, though, they can be removed from and re-added to your weapon whenever you like, meaning you can change the bonuses of your Shushumi before every fight. Unequipping fragments is done by equipping a number of fragments exceeding the weapon's capacity, which may or may not vary with the required level to use the weapon.
 * You can add up to a fixed number of Fragments (how this is calculated for any given weapon is currently unknown) to your Shushumi at a given time (NB: Five Minor Fragments of Shushu Soul can be added to the level 50 weapon used for testing, but only one for any given stat. That is, you can't equip, say, two Vitality bonuses. However, certain fragments are 'too powerful' to be added to the weapon - in this case, a Fragment of Critical Hit. Different weapons seem to have different capacities too, even though the weapons are the same level. E.g. Shovel Vett could take a Major Fragment of Strength, as well as a Minor Fragment of a Stat (Agi, Cha, Int), Where as Dagger Nica could not. Even though they both require level 50 to use.)
 * Fragments of Shushu's soul can no longer be shattered into Smithmagic Runes.
