'T'sais' (Jack Vance d20)

Michael O. Varhola

In the short story "T'sais," an artificial woman created by a wizard journeys from the mystical plane where she was created to the Dying Earth. The following type of magic item is inspired by the rapier she carries.There were any number of things from this story that could have been adapted to d20 stats but this one seemed especially fun and appropriate.

 

Living Weapon
This type of weapon has its own intrinsic fighting ability and, when wielded, can have either its own base attack bonus or that of its user applied to attacks such weapons cannot attack on their own. When created, a weapon of this sort can be imbued with a base attack bonus of up to +1 for every two caster levels of its creator (e.g., +3 for a 6th-level caster). Such weapons also receive an additional +1 on their attacks for of being masterwork quality. The wielder's own Strength or Dexterity modifiers, as appropriate, are still used to modify attacks and and the damage they inflict. 

If someone wielding such a weapon attempts to use their own base attack bonus rather than that possessed by the weapon, regardless of which is greater, all his attacks with it will suffer a -2 attack penalty.  

A weapon of this sort might also be enchanted as a +1 or more powerful weapon, but this is very rare and the regular cost of the weapon would stack with that of the traditional enhancement. 

An intelligent weapon of this sort could, at the DM's option, gain experience, improve its base attack bonus, and perhaps even gain appropriate Feats.
