Name: Ectoplasm Cannon
Appearance:

A medium sized cannon colored in pure black with various linear symbols that are a type of transmutation marking which is made to activate the cannon. These lines are "tap" lines, which are virtually equivalent to transmutation circles. These "tap" lines, however, are used for items that are to perform an alchemical function rather than traditional circles, which would simply use alchemical energy to alter to shape and function of one object, thereby transforming it into a different one. This cannon is very centered and has 8 legs that support its weight completely. Though usually pointing upwards, the cannon has very small hinges that allow the cannon to rotate and maneuver itself to fire at its target at will. Though the cannon is about 8 feet long when pointing upward, a length that one may not consider very well for distant targets, this cannon is actually very capable of striking down targets up to 68 feet away with an amount of power equivalent to the amount that could be inflicted from point-blank range. This machine is truly formed from the mind of an alchemical genius.
Effects: Only one Ectoplasm Cannon can exist on the field at a time. This cannon can continue to be summoned as long as the user rolls an Item dice to summon it. This item's effects can only be activated by a Spellcaster/Alchemist. By rolling 2 special dice and offering a Zombie-type creature, this cannon automatically inflicts damage to a target equal to the creature's remaining HP that was offered. The one that activates this must pay 500 Tsukara to activate this cannon. The amount of zombies that can be offered is equal to the amount of Special Dice rolled in multiples of 2. Simply put, rolling 2 Special Dice allows the user to offer 1 Zombie, 4 Special Dice will allow the offering of 2 Zombies, 6 Special Dice to offer 3 Zombies, etc.
HP: 1000/1000
History: Being one of the few alchemists capable of performing transmutations on living creatures, Rentu discovered a way to use his skill to protect himself and those that he wished to protect. Rentu, not being a very good physical fighter, designed weapons like cannons that he could use to inflict damage. Cannons, however, required ammunition to maintain and in order to be useful in battle, a cannon would either need to be small like a gun, or require very little ammunition which would most likely mean that it would only last for a short amount of time, and possibly have very little firepower. Rentu, being the brilliant demon that he is, discovered another option: A medium sized, powerful cannon, with creatures as ammunition that could be summoned by way of capsules. This would allow it to be easy to transport while still being efficient in battle. By making zombies, creatures that are technically neither dead nor alive, he "recycle" his creatures and use them as his firepower. Using his own method of alchemy, known as "tapping" something with tap lines rather than transmuting with transmutation circles, he could create items that can use artificial alchemy. By doing so, he successfully created the Ectoplasm Cannon.
Quantity: 1

I'm going to have to deny this idea. The fact that you only pay 500 Tsuakara to allow yourself to deal damage beyond your reach in a shorter amount of time, it doesn't seem to be well-balanced.
