Create Fragments

Arranging the material components around you, you can spend 1 hour to take a fragment of the enchantment on a magical weapon and imbue it into a new vessel. The new vessel is formed of whatever weapon material you used as a component, and takes the form of a simple or martial weapon. If the original enchantment deals damage, the damage of the fragment enchantment is decreased thusly: fixed damage is halved (rounding down) and any damage dice decrease in size (eg. an enchantment that deals d6+4 fire damage becomes d4+2 fire damage, and an enchantment that does d4+5 force damage becomes 2 force damage). The same degeneration of potency occurs to the original enchantment for every 2 fragments formed of it.

If this magic item is sentient, it must be willing, or fail a will (Wisdom) saving throw against your spell save DC. Additionally, the personality a weapon is fragmented, with the new vessel embodying only a single aspect, such as logic, anger, trust, or memory.

Regardless of casting method, the necessary material components are always required. 

For each level of spell slot above 5th, the number of fragments and subsequent vessels increases by 1.
