The outcome was disappointing, but it was a step in the right direction. They continued to increase the amount of divine crystals while trying to achieve the lowest quality.
They were eventually able to achieve a transmutation of 100 divine crystals into a +1 Strength divine sword at the cost of 100 divine energy. Next, they were able to convert 1,000 divine crystals into a +1 Strength divine sword for the low cost of 10 units of divine energy.
They couldn't reduce the cost of divine energy no matter how much they increased the amount of divine crystals after that. They needed to spend at least 10 units of divine energy for the transmutation. What they got with the increase in divine crystals was an increase in the power of the divine weapon.
They have a long way to go, as they have to test for divinity and soul gold too. Those are just materials. They still have to test for the quality of divine weapons too. It will cost them time and divine energy.
