I'm still not a fan of the hydration thing, as that's really more of a general life rule than a seblance specific limitation, but other than that it's fine,

Audial/Visual cues aren't always something that is heard in-universe. No one seems to know what Pyrrha's semblance is despite her using it pretty hevily in her fights, and she has a black outline around objects she's manipulating. Emerald's semblance makes that metallic sort of noise every time she uses it, despite it being a pretty big indicator that she is using her semblance, suggesting it's an out-of-universe thing. Some semblances only have audio/visual effects that we as the watchers can hear, to let us know when they are using it.

As for the semblance itself; eh. We've got multiple interations of it on the semblance thread, including one I made myself that does the exact same thing. So while it works, I wouldn't expect it to go on the SSMASLE at the top of the thread any time soon.
