Hi JeSuisR,
With your craftmanship, the rotation 1 should suit the best. You say that you dont have enough CP to complete the craft. Did you use the Trick of the trade skill when you get some "Good" condition on your materials ? The guide states :
It is very unlikely that you did not get two Good conditions. It never happened to me if I remember correctly. The rotation does use 387 + 40 CP. Consequently, if you did not cast Trick of the Trade at least two times, you will miss some CP.This first rotation is a 12 Hasty Touch rotation that requires 409 craftmanship and 387 CP's. It needs at least two TOTT to be completed.
Other question : does the Furnace Ring have 445/4980 difficulty/quality and 80 durability? I did not craft this item.
The rotations do work, but only in the exact conditions of the guide. If the difficulty / quality / durability is different, feel free to say, I will prepare a rotation and add an entry to my rotation guide.
