I may or may not have decided to take the Linguist Feat instead of Observant, because I feel Gavin would have learned many of these languages both in his noble education, and while traveling the world. And I like the idea of creating ciphers only my group can read. Just trying to figure out all those extra languages, since I can know Common, Elvish, and four extras (one for race and three for the feat).
I know i can use Comprehend Languages or Tongues, but those take up valuable spells known, and cost spell slots. I still might take Comprehend Languages, but I don't need both.
