The Treble Sword

This sword is an intelligent +5 long sword.  It is CE and will turn 
the user CE unless they make a will save of 30.  It is also a keen 
and vorpal. It will talk with the user telepathically.  The users
cannot sell the sword due to that the sword will not want to be sold. The only way dispose of this sword is to wish it away.  And the 
users cannot make this wish.  It also grants the users 120 hp.  
The users hp cannot increase with level or be magically increased.  
If the user kills a Chaotic Evil creature the lose hp equal to the
number of hit die of that creature, example if the user kills a 
Balor, it has 13 hit die so the user would lose 13 hp permanently 
and can not be recovered.
