Magic: Leveling Equipment

Description:
Leveling Equipment are equipment that can grow.

Almost all types can be levelling equipment. The exception are any consumable.

Types:
There are a few types of Leveling Equipment.

The Birth Type:
When created, it is already one. One can be made into a Birth Type by making it the normal way, through soul killing which is to use the equipment to gather enough souls, blood killing which is to soak the equipment in enough blood from any intelligent being.

The World Type:
It is created by the world.

The Dungeon Type:
The Dungeon has generated one.

Spirit:
Leveling Equipment may end up being an Intelligent or Normal one.

An Intelligent one can learn, like a Living Weapon. They can even gain skills more easily and learn Transformation magic.

A Normal One cannot learn so it is very difficult for it to gain skills.
