Are there any safety measures for people that fall off their broom? You know, so non-lethal force doesn't become lethal force.
Given that unlike the test with the pillar, where the officials and staff conducting the trials
explicitly were mentioned showing up and putting up barriers to both shield the audience and to rein force the pillars, I'm of two minds regarding this.
1) There are no safety measures, until someone does fall off their broom or look like they're about to crash - at which point the officials/staff will interfere by casting some sort of cushioning spell or otherwise soften/prevent the full-on bellyflop onto solid ground.
2) There are no safety measures and people are responsible for not eating dirt themselves. This is based on anime/manga in a setting of magic and fantasy. Falling from your broom and face-planting into the dirt isn't necessarily something that'd kill you unlike in real life. After all, people get hit by fireballs or toxic gas or lasers or a myriad of other hings in Black Clover and don't die. It's only in SRS plot moments where people actually seem to be able to "die".
Of course, I'm just guessing here and don't actually have any answer. Could be that Zeroth has something entirely different in mind.
