Honestly, the idea that a sound magician is useless I find strange. Think about the applications solely for battle. Using resonant frequencies to boil your enemies, high pitched noises to disable the animals, easier recon work, you could literally use sound to blast holes into objects How is it useless?
LtKaita:From the sound of it, high magical energy and aptitude is required for the stuff you said, so only a few people like MC could pull it off. Compared to more mainstream elements like fire/water/earth/etc, where it wouldn't take a lot of effort to condense a fireball or an ice spear and chuck it at the local wildlife. Even with low talent, those elements would still be useful. Whereas with low talent and something like sound magic, you could hear better and work as a radar tech or sound engineer, and that's it lol.
Alright, a little rushed. I do have to say that I hate being teased with "this person is this way because of 'that'" just friggin tell us. A lot of authors seem to use 'that'because they can't quite think of what they want to do, sometimes they completely forget about it and we, the readers, are left hanging. Either reveal it right away or just ignore mentioning it and reveal it later. Don't act like you're hiding something super special.
