I understand that it's normal (I see it happen a lot), but it doesn't look like it's supposed to be that way. If they just coded it so that it was x% chance of doing normal damage to something that was immune to physical, the damage wouldn't be the same on both arrows when two arrows do normal damage. They would be independent of each other. Also, it would be possible to do normal damage on 3 or 4 of my arrows, and I've never seen that either. (Of course, it's possible that that could happen and I just haven't seen it because the probability would be (small chance)^3 or (small chance)^4, but w/e.)

Also, just saying it's normal doesn't tell me why it happens, unless you're proposing that they coded it that way on purpose.
