After being able to mute myself for a few seconds, I knew for a fact that sound magic was possible.
Aside from eliminating the sound waves, I could also amplify them, making my voice sound as loud as a speaker. Maybe even louder.
However, I didn't try it, knowing it was nighttime in the castle. The least I needed at that moment was a bunch of people barging into my room, thinking something was wrong.
As I started to create the enchantment, I used one of the small rubies to see how much magic it could take before shattering. To my surprise, it could take quite a bit.
With the first ruby turned to dust, I grabbed another one and kept the magic dose smaller. However, as soon as the spell turned into an enchantment, the second ruby shattered, too.
'Hmm. It can contain raw magic, but it can't hold the full enchantment…' I thought, Vespera watching me work closely as she didn't want to miss any details.
