A few times. It’s pretty painful, especially if it’s to the bulb at the end, which is very sensitive. Damage can result in various problems with hearing others’ voices. Maybe it makes the colors of their voices seem off in that antennae, or too dark, or just generally distorted.
I got my right antennae damaged pretty badly a few lives ago, and that was really a hastle. For the rest of that life I could barely hear anything with it, and sometimes the weird static it picked up would give me migraines.
We’re pretty careful with them for that reason.
