To about clarify about the INT mod bonus to a skill of your choice. Based on the INT mod, you can add the proficiency bonus to that new skill, or add it again to a skill you are already proficient in. You can do this an x number of times based on the INT mod. Since your characters are currently level 2, your proficiency bonus is +2. Adding this bonus to an already proficient skill is called giving it "expertise" and can only be done once. 

So if you INT mod is 2, than you can choose two skills to become proficient, or if the character is already proficient in a skill, they can expertise in it.

Does that help clarify how this works for the INT mod skills/language bonus?

Also felt like typing thanks for the table idea for the characters, I may add it in the new thread within the first post of the character tab to help organize things.
