Hi everyone. Just needed a little bit of clarification on how many attacks a TEP genestealer should make when it charges.

I ran the Price of Hubris adventure last week and ruled that they could make 4 attacks on the charge (lightning attack + multiple limbs + preternatural speed) but one of my players pointed out near the end of the session that multiple limbs does state that you get an extra attack only when making a full attack action and preternatural speed says that you get to make a swift or lightning attack when you charge - i.e. technically not a full attack.

I think with hindsight that the stealers probably should only get 3 attacks on the charge and 4 when they stand still and full attack but how have other GMs run it and what do you guys think?

Your player was correct, the wording of preternatural speed is the same reason a death cultist can not make use of two weapon fighting on a charge along with thier lightning attack
