Vassal Weapons

The Vassal Weapons (眷属器) are entities, they are spirits of the vassal weapons that come from another world prior to being summoned. They decide the candidate to be forcefully summoned to another world to wield, however, different to the legendary weapons, these weapons has the ability to be summoned without a candidate present, giving the ability for the locals of the world to wield them if they prove themselves worthy. The users who wield these weapons are given the title of Vassal Weapons Holders or Vassal Heroes.

The name of the weapons may differ depending on the world they reside, in Raphtalia's world, these weapons are referred to as the Seven Star Weapons (七星武器) and the users that wield them are given the title of Seven Star Hero. The locals of her world are unaware of the present of the eighth vassal weapon. There are two Vassal Weapons per every Legendary Weapon and their purpose is to help assist in protecting their world from the waves.

Origins
The origins of the vassal weapons are shrouded in mystery, they have a deep tie with the Legendary Weapons and their respective worlds.

The role of the vassal weapon was initially believed to be used to invade worlds which are fusing with their own, to eliminate the legendary heroes. Successfully eliminating all the legendary heroes should save their own home but at the cost of destroying another world. The role of the vassal weapons are now believed to assist the legendary weapons and transport to other worlds to strengthen their own weapon.

Summoning & Selection
The vassal weapons were summoned through rituals, prior to being summoned they can be summoned with or without a candidate being present. When a wielder is deceased, the weapon chooses to roam the world or remain in a certain location in search of a new candidate that proves their potential.

Function
Vassal Weapons have less potential power than the Legendary Weapons, but make up for it by having fewer restrictive functions.

All weapons possess a gem that acts as the functional matrix to activate abilities, this gem persists through transformations. Vassal weapons specialize in fighting across world, but they will become faulty when their home world is destroyed.


 * Restrictions


 * Possessors may not equip weapons that are not of the same class as the Legendary Weapon itself. If they attempt to handle another weapon, they will be zapped.
 * Possessors cannot remove the Legendary Weapon from their bodies. If they throw it away, it will appear back in their hands
 * Unlike the Four Cardinal weapons which choose and adhere to the chosen heroes until death, Vassal weapons without a chosen hero aren't strict whoever wields them. This is evident in Mald's case, who temporarily wielded the Vassal Axe but only used it as a regular weapon. However, Vassal weapons cannot be used to their maximum potential unless it has chosen a hero and resonated with him/her (as evident in Raphtalia's case being able to wield the Vassal Katana in Glass' world). Once the Vassal weapon has chosen and bound to the hero, the person wielding it cannot use a different weapon other than the same class as the Legendary Weapon.
