SRD:Minus 2 Sword

–2 Sword, Cursed
This longsword performs well against targets in practice, but when used against an opponent in combat, it causes its wielder to take a –2 penalty on attack rolls.

All damage dealt is also reduced by 2 points, but never below a minimum of 1 point of damage on any successful hit. After one week in a character’s possession, the sword always forces that character to employ it rather than another weapon. The sword’s owner automatically draws it and fights with it even when she meant to draw or ready some other weapon. The sword can be gotten rid of only by means of limited wish, wish, or miracle.

Strong evocation; CL 15th; Craft Magic Arms and Armor, bestow curse, and limited wish or miracle; Price 1,500 gp.
