/*
	Impactscript for Animate Tree.
	
	Animate Tree (Sp): At 8th level, a verdant lord	can 
	animate a tree within 180 feet of him once per day. It 
	takes a full round for a tree to uproot itself; 
	thereafter it has a speed of 30 feet and fights as a 
	treant with respect to attacks and damage. The animated 
	tree gains a number of bonus Hit Dice equal to the 
	number of verdant lord levels the character possesses. 
	Though its Intelligence score is only 2 while animated, 
	the tree automatically understands the verdant lord’s 
	commands. The character can return the animated tree to 
	its normal state at will, and it automatically returns 
	to its normal state if it dies or if the verdant lord 
	who animated it is incapacitated or moves out of range. 
	
	Once the tree returns to its normal state by any means, 
	the verdant lord cannot animate another tree for 24 hours.
