Sword of Truth

Created long ago to destroy arcane magic uses, this intelligent +2 bane longsword became cursed, turning into the Sword of Lies, and was incarcerated in the Banewarrens. It remains dedicated to destroying arcane spellcasters, however. Should the evil curse on this blade can be removed by a 20th-level caster, it will return to its original alignment and abilities, listed here.

Blessing of Fervor (Sp): When in pursuit of its purpose (killing arcane spell casters), the Sword of Truth may cast blessing of fervor at will. Targets may only use the metamagic option of this spell on devine spells.

Detect Magic (Sp): The Sword of Truth may cast detect magic at will, but only for its own purposes; its wielder remains unaware of the sword's use of this ability, or its results (unless he or she has some other ability to see spell effects).

Bane (Ex): As a bane weapon, the Sword of Truth gains a +2 to hit (and deals an additional +2d6 damage) to arcane spell casters.

Speech (Su): Communicates verbally in Common.

True Sight (Sp): The Sword of Truth provides both it and its wielder with true seeing continually.

Spell Resistance (Su): When in pursuit of its purpose (killing arcane spell casters), the Sword of Truth may cast spell resistance at will. The sword also gains this resistance.

Strongly Aligned: Non-good characters who try to wield the Sword of Truth gain a temporary negative level. This cannot be removed while character wields the weapon. If they relinquish the sword they gain an immediate save to remove the level.
