There are traps inside of ruins that can generate the loathsome sound of a mandragora's cry. If we carried around something similar to that, that could activate Reszurre's "song" when necessary, we may be able to use it as an animal repellent. It's worth a shot, at least.

I'll... give it a try...

I want to try... helping out...!

I'll reproduce the vibrations generated by her "song" and engrave the sound waves into a mana quartz used as the base; that way, anyone that pours mana into it should be able to play them back... Putting quality aside...

You want me to... sing toward this stone?
