Cerebral Implants
Commonly used to repair a severely damaged brain or (hopefully) augment its abilities, these often-risky implant systems represent a major step from simply replacing a limb to altering a character from human to mechanism.
Common-level implants can restore paralysed and brain-damaged users to a semblance of normality, but with a permanent loss of 1d10 points from the character's Weapon Skill, Ballistic Skill, Agility, Intelligence, and Fellowship characteristics.
• Poor versions restore brain function, but destroy the subject's personality and memories, rendering them no better than a servitor, and as such are unsuitable for PCs.
• Good cerebral implants are very rare even among high ranking Imperial officials, and are exceedingly difficult to acquire, becoming Near Unique in Availability.
These grant the user the Unnatural Intelligence (2) trait (see page 139) and a +20 bonus to Logic and Lore tests, thanks to the superior mental capabilities he now enjoys.
