Just a quick update to fix some typos pointed out by Sootopolis on Steam.

Also, if you're having trouble getting the High Price ending while following the guide, and keep getting Echo instead:

That's because the goblets are somewhat random. You'll know you're getting the Echo ending if the player feels cold from drinking from the goblet. Scroll back and pick a different goblet. The player should feel warm.

I'll add this to the guide later.
