CURSEWEAPON 'CURSE WEAPON

CURSE WEAPON
Syntax: cast 'curse weapon' <object>

Necromancers can place a curse upon their weapons, causing it to be 
irremovable and unable to be dropped.  However, the weapon cannot avoid 
damage when trying to curse it, thus the blade might suffer some penalties 
upon each attempt.  There is even a chance the weapon cannot withstand the 
curse, and be destroyed.
