Shadow on the Moon

Anyone who could construct a stable Spell Model could become a Wizard — that was the Wizards' ultimate secret!

A Wizard's Secret

Merlin lowered his head and watched his finger turned into a faint white. His mind rushed with many thoughts.

Glacial Finger was truly powerful but it was not easy to cultivate. One had to meet many conditions beforehand. Wizard Heghar had reached Glacial Finger for a long time now but he was still unable to fully cultivate the spell. The main reason was that he was already a First-level Spell Caster when he first cultivated Glacial Finger.

However, Wizard Heghar had not even constructed Frigid Ice. Furthermore, he was not as fortunate as Merlin, who was able to retrieve the hundred years' ice bone marrow.

In order to cultivate Glacial Finger, he would first have to construct the very complicated First-level spell, Frigid Ice. Then, he would have to obtain the precious hundred years' bone marrow. Only then, he was able to meet the conditions to cultivate Glacial Finger.

Due to a string of lucky coincidences, Merlin was able to cultivate Glacial Finger.
