Collateral Summoners can use body parts as collateral in order to call forth external objects known as "Summon Beasts". The more the body part affects the users life the stronger the summon beast called forth will be. If a summon beast is destroyed its considered defaulting on the contract and the part offered up as collateral is also destroyed. As summon beasts can only perform simple orders, how one orders them about is imperative.
