+      <description>At the start of each battle round, pick which Canticle of the Omnissiah from the table below is in effect for the duration of the battle round. The same Canticle may not be picked twice during the same battle.
+
+Alternatively, you can randomly determine which Canticle of the Omnissiah is in effect by rolling a D6 and consulting the table below. Note that if you randomly determine a Canticle, it takes effect even if the same Canticle has been in effect earlier in the battle.
+
+1. Incantation of the Iron Soul:
+You can re-roll failed Nerve tests for models in your kill team.
+
+2. Litany of the Electromancer:
+Roll a D6 for each enemy model within 1&quot; of any models in your kill team at the start of the Fight phase.  On a 6, that enemy model suffers 1 mortal wound.
+
+3. Chant of the Remorseless Fist:
+Re-roll hit rolls of 1 for models in your kill team in the Fight phase.
+
+4. Shroudpsalm:
+When an enemy player makes a roll for a shooting attack that targets a model from your kill team, and that model is obscured, that hit roll suffers and additional -1 modifier.
+
+5. Invocation of the Machine Might:
+Add 1 to the Strength characteristic of models in your kill team.
+
+6. Benediction of the Omnissiah:
+Re-roll hit rolls of 1 for models in your kill team in the Shooting phase.</description>
