Psyker unit that specializes in debuffs.
Wyrdvane Psykers transform the howling might of the Warp into a deadly weapon of Imperial supremacy. They are formed from those Scholastica Psykana inductees not able to control their burgeoning powers without guidance and aid. As individuals, such psykers are unpredictable and unsafe. Yet working in concert, these deadly mutants can be a valuable asset.
