Cultivated Humans:  These mutant humans are grown in giant patches of soil that create mutants that resemble humans and a plant.  They have no free will or soul, so they can not feel pain.  These mutants are used like a regular member in a fight, but they can not train or learn moves, just punch.  Each one of their stats are 100, except for HP (300). One costs $500

Shadow Sword:  A powerful sword that is full of evil.  When struck with the sword, you are turned into a demon that is under complete control of the sword's owner (in other words, you must do everything they say and cannot act on your own).  The only way you can be returned to normal is if someone retrieves the antidote within the sword.  $6,000

Forlorn Hope: A mirror that is full of a twisted magic that is part evil and good. This mirror grants any wish of the user (to an extent), but the user must pay the price of death if it is COMPLETELY evil (ie. death to someone).  The mirror can only be used once.  $2,500

Orb of Baast: A magical orb that allows the user to suck the soul of a person out of their body.  Once the soul is eaten, all stats are restored.  Can suck three souls per day. $2,000

Katan (A Copy of Hiei's Sword): A incredibly sharp blade that can be used in battle to damage an enemy.  It can be used through spirit energy which will increase its attack by X 1.5.  $1000

The Rose Whip is a beautiful weapon with a sinister ability. Its thorns can slice through any substance, even stone. The Rose Whip usually has the last word in any battle. $1000

The Banshee Shriek is a mystical sword with the ability to call forth lost souls into the ring of battle. It produces a terrible sound that literally drains the power from anyone not strong enough to resist its wail.  $6000

Metal Bat: Just like it sounds. A bat you can swing at people in order to hurt them.  When in battles, it acts like a fist, just with more power x1.5.  $50

Concentration Ring: An item designed just for the Spirit Gun.  This ring fits snugly on your finger and can be reused.  When attacking with it, it does x3 the damage of a normal spirit gun.  $500

Med Kit: Heals ¼ of maximum hp. $50

Med Kit S: Heals ½ of maximum Hp.  $150
