Six stratagems, five at 1 CP and one at 2 CP, and two of them were rewritten in this pack.
Tireless Fervour had its whole Effect section rewritten and now has two parts. First: if your unit made an advance or fall-back move this turn, that move does not prevent it declaring a charge. Second, optionally: your unit can re-roll charge rolls, on condition that it ends that charge move engaged with an enemy unit engaged with a friendly CHARACTER unit.
That second part is a real choice with a real string attached. Opt in when you actually want to pile into the fight your character is already in, and decline it when you do not.
The Downtrodden Rise costs 2 CP, had its When and Effect sections rewritten, and is the detachment's escape hatch from the marker economy: one qualifying hybrid unit in Cult Ambush can be set up without using a Cult Ambush marker, anywhere more than 6 inches horizontally from all enemy units. Against an opponent who has spent the game deleting your markers, that is worth double the command points.
Frenzied Devotion improves the Attacks and Weapon Skill of melee weapons on models in a qualifying unit, excluding Characters, by 1, and gives those weapons [HAZARDOUS]. The hazardous is a genuine cost on a large squad, so spend this on a fight that decides something.
Transcendent Celerity gives a qualifying unit [ASSAULT] on its ranged weapons, which is what lets a squad Advance onto an objective and still contribute shooting.
Vengeance for the Martyr! fires just after an enemy destroys one of your Genestealer Cults CHARACTER models: target another Genestealer Cults character, and for the rest of the battle your Acolyte, Metamorph and Neophyte models re-roll Hit rolls of 1 against that enemy unit, upgraded to a full Hit re-roll if the destroyed character was a Magus, Primus or Acolyte Iconward. The pack's FAQ confirms you do need another Genestealer Cults character on the battlefield or in Reserves to use it.
The Path of Anguish fires just after an enemy has shot: one ACOLYTE HYBRIDS or NEOPHYTE HYBRIDS unit that lost models makes a D6 inch move that must end as close as possible to the nearest enemy unit, and may end within Engagement Range of it. Being shot at moves you closer to the enemy, which is a very Genestealer Cults way to be punished.
