So I got a bit of a question here.
Last weekend I played grey knights with my tyranids and while I still won, there was a bit of confusion regarding force weapons.
Question number 1: Do force cause instant death immediately after they wound or at the end of the phase? Like in past editions.
Question number 2: Can a force weapon (strength 4) wound and insta kill a creature double it's strength? (T9)
Question number 3: In a combat involving a drago wing (ten terminators + Drago) against 2 trygons, 1 harpy, 1 hive tyrant, and 6 raveners, can the grey knights divide their psychic attack against multiple models to cause instant death or is the activation of their force weapon a one power for the whole squad? If every single model can insta kill a different monstrous creature (especially if question number one is immediately after they wound) I find that a bit broken.
