Description: When determining the assault result, add one to your assault results if there is one or more friendly units with an Icon of Chaos locked in that combat.
If you place the first model of a deep striking friendly unit within 6" of an Icon of Chaos, the following rules apply:
If the deep striking unit and the unit with the Icon have the same daemonic alignment, do not scatter.
If the deep striking unit and the unit with the Icon have different daemonic alignments but are all Daemons, scatter only D6".
If there are non-Daemons in either unit, the Icon has no effect.
