This greater necromatic spell creates an undead mage.  The mage follows 
the caster as a charmed monster, serving until it is destroyed.  All 
experience gained by the undead servant is transfered to the caster. 
There is no time limit to the creature's existance, but the caster is 
limited to controlling a number of undead equal to (level+1)/10 
(minimum 1).
