The Transcendent Forge:

The owner of this wonder may sacrifice artifacts into this wonder in order to melt them down into "Raw Material". This Raw Material may be used as a substitute for progress points in order to upgrade or create non-mythical artifacts. In order to melt an artifact down into Raw Material, it must be placed into the wonder for a certain amount of time. Only two artifacts may be in the process of melting down, and it takes an amount of sessions, and grants an amount of Raw Material equal to the below list: Mundane: 1 Session (2 Raw Materials) Good: 1 Session (5 Raw Materials) Great: 1 Sessions (9 Raw Materials) Legendary: 2 Sessions (14 Raw Materials) Mythical: 3 Sessions (30 Raw Materials) There is also only one slot for an artifact being made, or upgraded at one time. Once an artifact is placed inside the wonder in order to be upgraded, it cannot be used, worked on by mech-rps, or removed until it is done. This wonder cannot function without the Hamner of Creation equipped by its owner. If it is lost, it will be returned to the owner in 1d8 sessions, twice this if it is destroyed. If it is stolen or unequipped, the wonder will go inert until it is recovered and reequipped. All artifacts created in this wonder have a 10% chance of being of a quality higher than expected. Upon artifact creation, the owner can risk a 20% chance of destruction to grant the artifact a random additional effect. Additionally, this wonder does not function without the (Forge) district, and consumes 1d4+1 (Bronze) each session. Failure to meet this will render the wonder unusable for 1d2+2 sessions. The wonder may hold up to 30 Raw Materials at a time, and will generate one a session.
