Thrall Bred

 
Prerequisite(s): Humanoid, Con 13+
 
Benefit: You can designate a single creature as your special charge. When you are within 30' of this creature, you gain a +1 morale bonus on all damage rolls and saving throws. If your special charge is not within 30', is dead or incapacitiated, you incur a -2 morale penalty to damage rolls and saving throws. You can designate a special charge only once per month. If your charge dies or abandons you, you take the morale penalty until you have the opportunity to choose a new charge (or choose to have no charge at all). You special charge must have more HD than you.
