This is a wonderful spell to enhance your familiar even further. It gives your familiar 3d4 int.and the ability to speak(if it so desires), and cast low level spells corresponding to the formentioned die roll but cannot cast spells above second level (although it would neat to see a weasle cast a fire ball!!!) the familiar is allowed two first level spells and one second level spell and one spell every five levels the caster gains after the initial casting of this spell.
The familiar is allowed a saveing throw of 12 i.e. if you roll below an 11 the spell fails, and if the spell fails, it cannot be cast upon the familiar for one year or the familiar is killed and the caster must make a system shock roll or die (see player's handbook "Find Familliar").
The material components are,an onyx statue of the familiar at least 4000 g.p. in value, powdered unicorn horn,and two scales of a gold dragon. All components are consumed by the casting.
