Decided to check out exactly how big the area was in terms of where you could potentially get hit by Crimson Specialist with a Trajectory Simulator...turns out it's big...like really big.
Didn't do the normal bomb drop, but that would only be a small bump on the back as despite also using the speed 1 template you can't control the orientation of the bomb template. Note: The measurements are to the outside of the shield tokens. It's about range 3.5 across the bubble and from the back to the front is over range 5. The TL:DR version, if you're in the same zip code as Crimson Specialist and she guesses right for bomb placement, she can totally hit you.
