Crystalline form enhances durability.
Crystalline Form is the biological ability of a DNA Alternate to transform their organic matter into a diamond form, making them virtually indestructible. Certain weaknesses vary from Alternate to Alternate, however, such as vulnerable (and shatterable) points in the body and, with enough effort, these could shatter the entire form. In specialized cases, though, these points render the wielder completely immobile, unable to move at all.
While in Crystalline Form, the Alternate may be able to focus energy passing through them into narrow, piercing beams. The Alternate may also become heavier or lighter while in Crystalline Form, depending on the specific case.
