No need to add another rank. it adds unnecessary complexity, not to mention historically there were only: Appentice, J-man, & Master. Novice is only used here as a way to define non-members who are working towards membership1.

Novice(non-member): Display interest in Weaponsmithing
Apprentice: Be intimately familiar with the weapon construction rules in the most current MOA, Be able to equip one's self with a weapon set of choice, or a shield and weapon. Know how to construct a safe blue, red, green, and white weapon. Know how to construct safe shields.
Journeyman: Learn how to construct safe and durable weapons of more than one kind. The Journeyman should grow to find a niche within the foamsmithing community and begin to pursue it (ie. archery, sword&board, spear, ect).
Master Weaponsmith: A master should be familiar with all aspects of advanced foamsmithing, but not necessarily know all techniques. A master foamsmith should at the very least know how and be able to construct a weapon from a chosen weapon category and implement the most advanced techniques and materials in the construction. Once the rank of master is attained, It is the master's responsibility to share this knowledge of advanced foamsmithing with others and actively pursue better designs and materials to benefit the Dagorhir community.
