Balance and Flavor!

Made a few quick balance changes to help make intuitive Relic combination choices or "Builds" feel as strong or as unique as they should.
While tweaks are minor, they can take a while to get just right because changing one part tends to indirectly nerf or buff a bunch of other things.
Seems to be in a better place than where it started so let me know how it feels on your end if you have some time to leave feedback :)

Changes:
- Hit Rating on a certain Relics has been improved to match with it's description / note
- Firebrush's magical attack power has been adjusted to better reflect it's threat level
- Royal Bones' physical attack power has been adjusted to provide more flexibility in the Relic combinations that can successfully fell it
- Main Character's Class has been changed from "Explorer" to "Otaku"
