Read the CP costs carefully. Two of these went up to 2CP in the current pack, which meaningfully changes how many you can fire per turn.
Rites of Fire (your Shooting phase, 1CP). Target one Adepta Sororitas unit that disembarked from a TRANSPORT this turn and has not shot. Until end of phase, each ranged attack against an enemy unit within 6 inches that is also within range of an objective marker adds 1 to the Wound roll; if models are destroyed, one of their units takes a Battle-shock test. Note the two conditions stack: within 6 inches AND on an objective. The pack rewrote this Effect section.
Shield of Aversion (your opponent's Shooting phase or the Fight phase, 1CP). Worsen the Armour Penetration of attacks against your unit by 1 until the attacking unit finishes. Also rewritten by the pack.
Righteous Blows (Fight phase, 1CP). Your unit's melee weapons gain [LETHAL HITS], and destroyed enemies force a Battle-shock test.
Carry Forth the Faithful (your Movement phase, before a TRANSPORT Advances, 1CP). Re-roll Advance rolls for it, and units can disembark even though it Advanced, making a shock disembark move.
Cleansing Flames (your Shooting phase, 2CP). Torrent weapons in your unit gain [DEVASTATING WOUNDS]. The pack raised this from 1CP to 2CP. It is still strong; it is no longer something you fire casually every turn.
Blazing Ire (your opponent's Shooting phase, 2CP). A unit embarked in a targeted TRANSPORT can disembark as if it were your Movement phase and shoot as if it were your Shooting phase, at the unit that shot. Also raised to 2CP.
Three of the six care about TRANSPORT models. That is not incidental: this is a mechanised detachment, and the Immolator is close to a requirement.
