Reward: The Ordo Malleus acknowledges the purge: one fighter gains a founding Sanctic power for free, OR the gang unlocks a one-off free requisition of a Strike or Terminator brother for its next battle. Claimable once each time the threshold is crossed.
The brotherhood keeps a tally of the warp-born it has sent screaming back into the immaterium, and the Ordo Malleus keeps count with it. This sub-plot advances as your gang banishes or takes Out of Action DAEMON and PSYKER fighters across the campaign; each time the running total crosses a declared threshold, the tally is struck and the reward claimed.
REWARD. The Ordo Malleus acknowledges the purge. One of your fighters gains a founding Sanctic power for free, or the gang unlocks a one-off free requisition of a Strike or Terminator brother for its next battle. The reward may be claimed once each time the threshold is crossed, so a brotherhood that hunts relentlessly is rewarded again and again for the count it keeps.
