An extremely rare example of psitech dating from before
the Scream, a precognitive nav chamber allows a character with at least
Precognition-2 psionic skill to assist in interstellar drills, sensing
impending shear alterations before they happen. The navigator
automatically succeeds on any spike drill check of difficulty 9 or less.
On a failed check, add 2 to the Spike Drive Mishap roll, limiting the
potential damage. On drilling in to the destination system, the psychic
has expended all Effort in the process.
