I’m new to Warhammer 40k and I’m trying to figure out how the shoot phase works. Here’s the scenario, Tempestus Scion unit has 3 models shoot their hot-shot lasguns at a guardsmen unit with 10 models. Hot-shot lasguns have rapid fire 1 and the guardsman unit is within 12 inches, so shots are doubled for a total of 6 shots from 3 attacks. All wounds go through and now we determine which guardsmen model needs to make saving roles. Here lies the question, do 3 models in the unit role 2 saves due to it being from 3 attacks, or do 6 units in the unit role 1 save for each shot?
