Crystal (InstanceTopic, 9)
From Compile Worlds
Crystals are naturally occurring objects in nature. A crystal's molecules form orderly, repeating patterns, unlike most substances, causing the larger varieties to have really cool geometric shapes. Ice is a very common example of something that can crystallize.
In Project Nanako, Nanako can cast powerful magic by using crystals arranged in geometric patterns. In Compile Worlds, as well as being able to do this herself, she taught her crystal magic to Beta and Theta when she saved them from Whitespace, and Omega later gained the ability by absorbing Theta. This allows them to create spells like Crystal Locust and Crystal Thunder. In any instance, this is a class of magic using a Crystal element. While not a Crystal element use, Witchcart claims she can turn any dissenters of her spontaneous and short-lived regime into crystal.
Crystal Magic is generally considered quite powerful. So far, the only zero revealed to be able to cast it is Beta. Omega uses Crystal magic, as well as Zeta's Arle-type magic in favor of the Fire elemental magic she was birthed with.
