Minimum Standards

Karl began the lesson. "Now that you both have the crafting skill. I will go over the basics with you. We are going to make rings that can store mana and increase Skill Power. Those will be the staple of our shop, so I want you both to learn how to make them right away." 

He wrote the rune on the chalkboard on the wall, including notes about stroke order and direction with depth changes, then gestured to the pile of wooden rings. 

"As Miss Loros got an early start, I will demonstrate one before you both make plain rings to practice on." He added.

Loros gestured to the side of the table, where dozens of ring blanks in various sizes were already made. They had only been roughly shaped into circles, and Karl realized that she had cored the same stick to make two different ring sizes from the same disc.

Very efficient use of materials.
