Sanctus

During deployment, you can set this unit up in ambush instead of on the battlefield. If this unit has the INFANTRY or BIKER keyword, you can either set it up in ambush or underground instead of on the battlefield.

When you set up a unit underground, it can emerge at the end of any of your Movement phases - set the unit up anywhere on the battlefield that is more than 9" from any enemy models.

When you set up a unit in ambush, place one ambush marker anywhere on the battlefield that is wholly within your deployment zone. You will need one ambush marker for each unit that will deploy in this way. If you set up a TRANSPORT in ambush, you must still tell your opponent what units are embarked within it when it is set up in ambush - do not set up separate ambush markers for units that start the battle embarked within a TRANSPORT, even if they have the Cult Ambush ability.

In matched play, units set up in ambush using this rule count as being set up on the battlefield for the purposes of Tactical Reserves.

For ambush markers, see Codex: Genestealer Cults p79.

Each time you fail a saving throw for a <CULT> CHARACTER model, and each time a <CULT> CHARACTER suffers a mortal wound, before allocating damage check to see if it is within 3" of any <CULT> or BROOD BROTHERS units with this ability. If it is, you can select one of those units and roll a D6; on a 4+ you do not inflict any damage on the character, but one model in the selected unit (your choice) is slain. Otherwise, the character suffers damage as normal.
