A class from Psychic Pshowdown. It resembles the Mechanist in a few ways, and uses minion based tactics.
However, it's minions appear to be made of crystals and gemstones, and while they are somewhat mechanical, and can be upgraded as such, they are capable of using psychic powers. The Crystalopher gains a few psionic powers, too, but it's minions have much stronger psychic powers.
