Great, thanks for the answer !

The battletome clearly states that the "impact abilities" of the various chariot units are unit-dependent (as opposed to model-dependent). In other words, a reinforced unit of 3 chariots would not hit any harder with its impact ability (be it Soulscent, Excess of Blades or Mutilating Blades) than a unit made of a single chariot. Is is an oversight, is it intentional, or am I misunderstanding something ?

If an artefact of power was offered at the Fane of Slaanesh, does it still count as being equipped by the hero for the purposes of the Slaanesh-specific "Coveted Riches" grand strategy ? As a reminder, here are the two rules : Coveted Riches: When the battle ends, you complete this grand strategy if there are no enemy units that have artefacts of power on the battlefield and there are 1 or more friendly units that have artefacts of power on the battlefield. Damned Conduit (Fane of Slaanesh) : At the start of your hero phase, you can pick 1 friendly Hedonites of Slaanesh Hero within 6" of this terrain feature to make a sacrifice. If you do so, that Hero suffers 1 mortal wound and you must roll a dice. On a 2+, add 1 to wound rolls for attacks made by that Hero until your next hero phase. If the Hero you picked has an artefact of power, instead of suffering 1 mortal wound, they can sacrifice that artefact of power. If they do so, that artefact of power can no longer be used and you must roll a dice. On a 2+, add 1 to wound rolls for attacks made by that Hero for the rest of the battle.
