Becoming a Dreadnaught
Becoming a colossal apostate is no easy thing. No state of the Octet would commission a Transfiguration with the Dreadnaught Chassis Reconception submodule even in the most dire of circumstances, and the material costs of increasing Essence for heretical Colossi is at least as great as for their orthodox counterparts. Some few manage to conceal their corruption long enough to con their sponsors out of at least the chassis of their upgrades, installing their own Void tech submodules by other means, but such solutions are far from perfect.
Eventually, nearly all Dreadnaughts come to rely upon the charm Transorganic Desecration Cyst (Alchemicals, Page 180) and its Retromorphic Dynamic Physiology submodule, but even this is insufficient on its own to reach the higher tiers of enlightenment. In order to increase his Essence to 6 or higher, an Apostate requires access to a vast stockpile of arcane materials with a total cost equivalent to Wealth ••••, and lacking the support of a sponsor state he must take specific action to acquire such vast resources.
