At this point in the game probably not many people will craft constelation weapons but I just had this idea. Later maybe it could also be used for Armonia recipes.
So to get to the point. Instead of providing Queen Hamaan with 12 tokens to choose recipe why not have her turn tokens into "constelation recipe token". This new token that combines all 12 symbols you can use to buy recipe from shop npc. Reason for this is when I want to take recipe from Hamaan right now I have no way of checking what runes I need for each weapon. It's not too hard to check online but not everyone knows the website to go to.
This might work for Armonia recipes as well and lessen pressure on certain crests and lower their price or balance the price of all 4 crest types. Similar to constelation, priest would offer "armonia recipe token" by giving him the right crest combinations.
