/*
	Impactscript for Shadow Servant.  
	(this is handled in the Familiar script)
	
	Shadow Servant (Su): At 1st level, your shadow familiar permanently
	transforms into a Medium shadow elemental. It loses all familiar 
	traits, but gains new abilities as your shadow servant.

	Should your shadow servant die, you can summon a replacement after
	24 hours pass. Your shadow servant cannot travel farther from you 
	than 30 feet + 10 feet for each of your master of shadow levels 
	(40 feet at 1st level and a maximum of 130 feet at 10th level). If 
	it is forcibly separated from you by more than this distance, the 
	servant dissipates instantly, and you must wait 24 hours to summon 
	a new one.
