COM AB:Soul of the Stormhost

The Redeemers of the Hammers of Sigmar break the
enemy force with waves of reinforcements that
never seem to end.
You can use this command ability when a friendly
HAMMERS OF SIGMAR REDEEMER unit is
destroyed. If you do so, roll a dice. On a 5+ a new
unit identical to the one that was destroyed is
added to your army. Set up the new unit
anywhere on the battlefield, more than 9"
from any enemy models.
