Had a situation come up the other day. My fire prism blasted a tightly packed squad of chaos marines that was partially in a forest and partially behind the forest. I hit 2 models squarely and partialed 2 models behind the forest, and actaully I got a partial hit on another CSM from another squad that was behind the forest, but one model of that 2nd squad was in the forest and a legal target.
1. Can all three CSMs that were behind the forest be killed? (All models behind the forest were LOS blocked no argument from me or my friend)
We agreed yes with a 5+ forest cover save for everyone, but we both admitted we were just guessing.
2. If I had a flamer template does that change the answer at all?
