[MERGED PR] Nerfs Rathen's Secret and Magic Missile spells

[Sord213]

Good changes, imo. Magic missile is incredibly strong considering it's a free spell every wizard gets. I'd probably also suggest cutting the damage down a bit, but that's just me.

And rathen's secret is.... rathen's secret. A mostly joke spell (haha he butt fall off) that has historically been extremely strong. It's going to take a while to find a good balancing point where it's not stupidly strong but also not completely worthless.
