Household Vessel

Household Vessels (眷属器, Kenzoku Ki) are objects (weapons, jewelry, accessories, etc) that hold importance to the Household Members of a Dungeon Capturer.

Acquiring
This person helps the Dungeon Capturer capture a Dungeon and forms a Household Vessel from that candidates Djinn, or if the assistant makes a strong connection with the Dungeon Capturer. When a Household Member first uses the power, a Familiar of the Djinn shows up and grants it to them. It seems that if the King Candidate does not have his/her Metal Vessel, the Assistant can not use their Household Vessel.

Activation
The activation of a household vessel actually has two stages the normal stage and the more powerful stage called Assimilation.

Assimilation is the fusion of one's self with the household spirit of the Djinn inside the metal vessel. By doing this the user becomes more powerful but at the cost of becoming less human. The more number of times a person performs assimilation the more they become less human, according to Masrur it begins with the body then the mind and last the heart.

Appearance
Household vessel is basically the same as Metal Vessel. They are made of metal objects that have deep meaning to the user.
