So, here's a scene idea from yours truly:
eagle brown falcon, Horus, is fighting against a necromancer that can stop time. So the necromancer obviously stops time, pulls out an MG 42, and shoots at Horus for 10 seconds. Using the average rate of fire, that's 200 rounds shot.
Time resumes and the bullets rip through Horus' shield.
For a few frames, we can see his back. The shoulder and the upper-left side are gone in a mist of blood. The wing is completely severed, the crop, stomach, and some of the air sacs got ripped out as well. Parts the ribcage can be seen too.
Then we cut to the other characters, seeing Horus fall out of the sky from afar, but the impact is obscured by a line of buildings.
In animation or live-action, this is a way of shocking the audience without being excessively gory. This can be accomplished because the visuals allow you to tell a lot in a few frames, making the death seem even more shocking and brutal.
However, text progresses at a snail's pace. Even after trimming and tidying the prose, you don't have to pause the book at the right frame to catch it. You have to choose between detail (the extent of the damage) and speed (the characters seeing what just happened). Sure, we're still flying half a ship, but it feels weaker for the reasons I stated above.
How can you convey suddenness when a lot is happening at once?
