Ignition Weapon

Ignition Weapons are a poweful type of weapon used in the Tower. They can take on the form of any type of weapon, the difference being that an Ignition weapon can be Ignited, releasing vast amounts of power and sometimes changing the form of the weapon.

Ignition weapons are supposedly quite rare on the lower Floors of the Tower, as Androssi was very surprised when she first saw Namaruda.

An incredibly famous and powerful group of ignition weapons are called the 13 Month Series.

A branch form of ignition weapons are Compression Weapon.
