Looking at the numbers:
We have 23 crossbow blueprints, but need another 11 to reach 100 stars.
We have 28 gun blueprints, but need another 6 to reach 100 stars.
We have 15 musical instrument blueprints, but need another 10 to reach 75 stars.
We have 22 cloak blueprints, but need another 12 to reach 100 stars.
We have 14 aura blueprints, but need another 9 to reach 69 stars.
We have 26 meal blueprints, but need another 8 to reach 100 stars.
We have 20 desert blueprints, but need another 9 to reach 85 stars.
Best case, we only have to wait for another 6 gun blueprints.
Worst case, we have to wait for another 12 cloak blueprints.
Notable of these are going to be those that give the most profit when sold, or the most xp when sold.
