Crystalmancy is a power that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is a form of sorcery used by the Troll civilization to manipulate and control the power of crystals, the most well-known users of which are Walter and Wendy Naugus.
Crystalmancy allows the users to encase anyone or anything in solid crystal. Should anything robotic become crystallized, its programming becomes susceptible to the spell-caster's commands and can be summoned to their aid as long as the machine is within a certain range.
