My suggestion is simple.
2 formulas dragons have for lairshaping contain product that are currently not being used.
Both the formulas for Lodestones (used for Maelstones creation) and the Imbued Bars contain a version for every metal currently ingame, while the Iron, Steel and Cobalt version is unused at this moment. We only have to use Bronze, Silver, Gold, Platinum, Mithril and Adamantium for lairshaping purposes.
These unused items are written out full:
1. Iron Lodestone
2. Steel Lodestone
3. Cobalt Lodestone
4. Imbued Iron Bar
5. Imbued Steel Bar
6. Imbued Cobalt Bar
Therefore I would like to suggest the removal of the unused items from both the Lodestones formula and the Imbued Bars formula.
Unless the devs have future plans for the above mentioned items of course.
In which case I would be curious to know what they will be used for...
